Lain, Sonia published the artcileDiscovery, in vivo activity, and mechanism of action of a small-molecule p53 activator, HPLC of Formula: 380315-80-0, the publication is Cancer Cell (2008), 13(5), 454-463, database is CAplus and MEDLINE.

We have carried out a cell-based screen aimed at discovering small mols. that activate p53 and have the potential to decrease tumor growth. Here, we describe one of our hit compounds, tenovin-1, along with a more water-soluble analog, tenovin-6. Via a yeast genetic screen, biochem. assays, and target validation studies in mammalian cells, we show that tenovins act through inhibition of the protein-deacetylating activities of SirT1 and SirT2, two important members of the sirtuin family. Tenovins are active on mammalian cells at one-digit micromolar concentrations and decrease tumor growth in vivo as single agents. This underscores the utility of these compounds as biol. tools for the study of sirtuin function as well as their potential therapeutic interest.

Makhortova, Nina R. published the artcileA screen for regulators of survival of motor neuron protein levels, HPLC of Formula: 380315-80-0, the publication is Nature Chemical Biology (2011), 7(8), 544-552, database is CAplus and MEDLINE.

The motor neuron disease spinal muscular atrophy (SMA) results from mutations that lead to low levels of the ubiquitously expressed protein survival of motor neuron (SMN). An ever-increasing collection of data suggests that therapeutics that elevate SMN may be effective in treating SMA. The authors executed an image-based screen of annotated chem. libraries and discovered several classes of compounds that were able to increase cellular SMN. Among the most important was the RTK-PI3K-AKT-GSK-3 signaling cascade. Chem. inhibitors of glycogen synthase kinase 3 (GSK-3) and short hairpin RNAs (shRNAs) directed against this target elevated SMN levels primarily by stabilizing the protein. It was particularly notable that GSK-3 chem. inhibitors were also effective in motor neurons, not only in elevating SMN levels, but also in blocking the death that was produced when SMN was acutely reduced by an SMN-specific shRNA. Thus, the authors have established a screen capable of detecting drug-like compounds that correct the main phenotypic change underlying SMA.

Pontiki, Eleni published the artcileHistone deacetylase inhibitors (HDACIs). Structure-activity relationships: history and new QSAR perspectives, HPLC of Formula: 380315-80-0, the publication is Medicinal Research Reviews (2012), 32(1), 1-165, database is CAplus and MEDLINE.

A review. Histone deacetylase (HDAC) inhibition is a recent, clin. validated therapeutic strategy for cancer treatment. HDAC inhibitors (HDACIs) block angiogenesis, arrest cell growth, and lead to differentiation and apoptosis in tumor cells. In this article, a survey of published quant. structure-activity relationships (QSARs) studies are presented and discussed in the hope of identifying the structural determinants for anticancer activity. Secondly a two-dimensional QSAR study was carried out on biol. results derived from various types of HDACIs and from different assays using the C-QSAR program of Biobyte. The QSAR anal. presented here is an attempt to organize the knowledge on the HDACIs with the purpose of designing new chem. entities with enhanced inhibitory potencies and to study the mechanism of action of the compounds This study revealed that lipophilicity is one of the most important determinants of activity. Addnl., steric factors such as the overall molar refractivity (CMR), molar volume (MgVol), the substituent’s molar refractivity (MR) (linear or parabola), or the sterimol parameters B₁ and L are important. Electronic parameters indicated as σ_p, are found to be present only in one case. © 2010 Wiley Periodicals, Inc. Med Res Rev 32:1-165, 2012.

Rausch, Keiko published the artcileScreening Bioactives Reveals Nanchangmycin as a Broad Spectrum Antiviral Active against Zika Virus, HPLC of Formula: 380315-80-0, the publication is Cell Reports (2017), 18(3), 804-815, database is CAplus and MEDLINE.

Zika virus is an emerging arthropod-borne flavivirus for which there are no vaccines or specific therapeutics. We screened a library of 2,000 bioactive compounds for their ability to block Zika virus infection in three distinct cell types with two different strains of Zika virus. Using a microscopy-based assay, we validated 38 drugs that inhibited Zika virus infection, including FDA-approved nucleoside analogs. Cells expressing high levels of the attachment factor AXL can be protected from infection with receptor tyrosine kinase inhibitors, while placental-derived cells that lack AXL expression are insensitive to this inhibition. Importantly, we identified nanchangmycin as a potent inhibitor of Zika virus entry across all cell types tested, including physiol. relevant primary cells. Nanchangmycin also was active against other medically relevant viruses, including West Nile, dengue, and chikungunya viruses that use a similar route of entry. This study provides a resource of small mols. to study Zika virus pathogenesis.

Grigoreva, Yu S published the artcile[The role of p53 in the regulation of proliferation and differentiation of the neural progenitors in mouse hippocampal organotypic culture]., Product Details of C20H23N3O2S, the publication is Rossiiskii fiziologicheskii zhurnal imeni I.M. Sechenova (2013), 99(10), 1160-74, database is MEDLINE.

In the present work we have studied the effects of p53 on the proliferation and differentiation of neural progenitor cells (NPC) in mouse hippocampal organotypic culture. To study the role of p53 the selective p53 inhibitor pifithrin-alpha (PFT) and activator tenovin 1 (TEN) were used in the experiments. Obtained data demonstrated that the injections of PFT did not affect on the amount of phospho-H3 positive cells in the subgranular zone of hippocampus. This data revealed that p53 inhibition does not change the proliferation level of the NPC. In opposite, at the TEN treatments we observed increased of the proliferation activity. Analysis of Pim-1 and Phb 1, which regulate cell cycle progression, demonstrated that p53 activation led to increased level of Pim-1 as well as the proliferation. Thus, our data correlate with published ones and proposed that Pim-1 positively regulates NPC cell cycle progression. In opposite to Pim-1, Phb 1 has anti-proliferative action. Our obtained data demonstrated that TEN diminished Phb 1 expression. Primarily PFT injections led to the increasing Phbl level, but then dramatically decreased it that accompanied with unchanged proliferation level. In other words, increased proliferation level after TEN treatments, which we observed, can be partly depend from the inhibition of anti-proliferative activity of Phb. In our study we demonstrated that both TEN and in a greater degree PFT stimulates neuronal differentiation by activation of CRMP-2 expression, but do not affect on gliogenesis. Thus, obtained data revealed that p53 is an important factor of neuronal differentiation and, probably, p53 action is mediated by cell cycle regulator protein such as Pim-1 and Phbl.

Singh, Chandra K published the artcileNovel downstream molecular targets of SIRT1 in melanoma: a quantitative proteomics approach., Computed Properties of 380315-80-0, the publication is Oncotarget (2014), 5(7), 1987-99, database is MEDLINE.

Melanoma is one of the most lethal forms of skin cancer and its incidence is continuing to rise in the United States. Therefore, novel mechanism and target-based strategies are needed for the management of this disease. SIRT1, a NAD(+)-dependent class III histone deacetylase, has been implicated in a variety of physiological processes and pathological conditions. We recently demonstrated that SIRT1 is upregulated in melanoma and its inhibition by a small-molecule, tenovin-1, inhibits cell proliferation and clonogenic survival of melanoma cells, possibly via activating p53. Here, we employed a gel free quantitative proteomics approach to identify the downstream effectors and targets of SIRT1 in melanoma. The human malignant melanoma, G361 cells were treated with tenovin-1 followed by protein extraction, in liquid trypsin digestion, and peptide analyses using nanoLC-MS/MS. A total of 1091 proteins were identified, of which 20 proteins showed significant differential expression with 95% confidence interval. These proteins were subjected to gene ontology and Ingenuity Pathway Analysis (IPA) to obtain the information regarding their biological and molecular functions. Real-Time qRT-PCR validation showed that five of these (PSAP, MYO1B, MOCOS, HIS1H4A and BUB3) were differentially expressed at mRNA levels. Based on their important role in cell cycle regulation, we selected to focus on BUB family proteins (BUB3, as well as BUB1 and BUBR1) for subsequent validation. The qRT-PCR and immunoblot analyses showed that tenovin-1 inhibition of SIRT1 resulted in a downregulation of BUB3, BUB1 and BUBR1 in multiple melanoma cell lines. Since tenovin-1 is an inhibitor of both SIRT1 and SIRT2, we employed lentivirus mediated silencing of SIRT1 and SIRT2 in G361 cells to determine if the observed effects on BUB family proteins are due to SIRT1- or SIRT2- inhibition. We found that only SIRT1 inhibition resulted in a decrease in BUB3, BUB1 and BUBR1. Our study identified the mitotic checkpoint regulator BUB family proteins as novel downstream targets of SIRT1. However, further validation is needed in appropriate models to confirm our findings and expand on our observations.

Lucera, Mark B. published the artcileHIV signaling through CD4 and CCR5 activates Rho family GTPases that are required for optimal infection of primary CD4+ T cells, Product Details of C20H23N3O2S, the publication is Retrovirology (2017), 4/1-4/13, database is CAplus and MEDLINE.

Background: HIV-1 hijacks host cell machinery to ensure successful replication, including cytoskeletal components for intracellular trafficking, nucleoproteins for pre-integration complex import, and the ESCRT pathway for assembly and budding. It is widely appreciated that cellular post-translational modifications (PTMs) regulate protein activity within cells; however, little is known about how PTMs influence HIV replication. Previously, we reported that blocking deacetylation of tubulin using histone deacetylase inhibitors promoted the kinetics and efficiency of early postentry viral events. To uncover addnl. PTMs that modulate entry and early post-entry stages in HIV infection, we employed a flow cytometric approach to assess a panel of small mol. inhibitors on viral fusion and LTR promoterdriven gene expression. Results: While viral fusion was not significantly affected, early post-entry viral events were modulated by drugs targeting multiple processes including histone deacetylation, methylation, and bromodomain inhibition. Most notably, we observed that inhibitors of the Rho GTPase family of cytoskeletal regulators-including RhoA, Cdc42, and Rho-associated kinase signaling pathways-significantly reduced viral infection. Using phosphoproteomics and a biochem. GTPase activation assay, we found that virion-induced signaling via CD4 and CCR5 activated Rho family GTPases including Rac1 and Cdc42 and led to widespread modification of GTPase signaling-associated factors. Conclusions: Together, these data demonstrate that HIV signaling activates members of the Rho GTPase family of cytoskeletal regulators that are required for optimal HIV infection of primary CD4+ T cells.

Hackett, Brent A. published the artcileSirtuin inhibitors are broadly antiviral against arboviruses, Related Products of amides-buliding-blocks, the publication is mBio (2019), 10(4), e01446-19/1-e01446-19/12, database is CAplus and MEDLINE.

Arthropod-borne viruses are diverse pathogens and are often associated with human disease. These viruses span multiple genera, including flaviviruses, alphaviruses, and bunyaviruses. In a high-throughput drug screen, we found that tenovin-1 was antiviral against the flaviviruses Zika virus and dengue virus. Tenovin-1 is a sirtuin inhibitor, and here we found that inhibition of sirtuins, but not inhibition of the related histone deacetylases, is potently antiviral against diverse arboviruses. Sirtuin inhibitors block infection of arboviruses in multiple human cell types. We found that sirtuin inhibitors arrest infection downstream of entry but that they do so at an early step, preventing the accumulation of viral RNA and protein. However, sirtuin inhibitors had no impact on the replication of flaviviral replicons, suggesting a defect in the establishment of replication. Consistent with this, we found that sirtuin inhibitors impacted double-stranded RNA (dsRNA) accumulation during flaviviral infection. Since these viruses infect vector insects, we also tested whether sirtuin inhibitors impacted infection of adult flies and found that these inhibitors blocked infection; therefore, they target highly conserved facets of replication. Taken together, these results suggest that sirtuin inhibitors represent a new class of potent host-targeting antivirals.

Based on some common structural features of known compounds interfering with p53 pathways and our previously synthesized benzamides, we synthesized new Et 5-(4-substituted benzamido)-1-phenyl-1H-pyrazole-4-carboxylates 26a-c, Et 5-(4-substituted benzamido)-1-(pyridin-2-yl)-1H-pyrazole-4-carboxylates 27a-c and N-(1H-indazol-6-yl)-4-substituted benzamides 31a,b bearing in the 4 position of the benzamido moiety the 2-phenylpropanamido or 2-phenoxyacetamido or cinnamamido groups. A preliminary test to evaluate the antiproliferative activity against human lung carcinoma H292 cells highlighted how compound 26c showed the best activity. This last was therefore selected for further studies with the aim to find the mechanism of action. Compound 26c induces intrinsic apoptotic pathway by activating p53 and is also able to activate TRAIL-inducing death pathway by promoting increase of DR4 and DR5 death receptors, downregulation of c-FLIP_L and caspase-8 activation.
