A series of novel 1,2,3-benzotriazin-4-one derivatives containing 4,5-dihydrothiazole-2-thiol were synthesized and characterized by H-1 NMR, C-13 NMR, F-19 NMR and HRMS. The bioassay results showed that compounds 3-(3-((4,5-dihydrothiazol-2-yl)thio)propyl)-7-methoxybenzo[d][1-3]triazin-4(3H)-one, 3-(3-((4,5-dihydrothiazol-2-yl)thio)propyl)-6-nitrobenzo[d][1-3]triazin-4(3H)-one, 7-chloro-3-(3-((4,5-dihydrothiazol-2-yl)thio)propyl)benzo[d][1-3]triazin-4(3H)-one exhibited good control efficacy against the cucumber root-knot nematode disease caused by Meloidogyne incognita at the concentration of 10.0 mg L-1 in vivo. Compound 7-chloro-3-(3-((4,5-dihydrothiazol-2-yl)thio)propyl)benzo[d][1-3]triazin-4(3H)-one showed excellent nematicidal activity with inhibition 68.3% at a concentration of 1.0 mg L-1. It suggested that the structure of 1,2,3-benzotriazin-4-one containing 4,5-dihydro-thiazole-2-thiol could be optimized further.

I found the field of Biochemistry & Molecular Biology; Pharmacology & Pharmacy; Chemistry very interesting. Saw the article A-ring and E-ring modifications of the cytotoxic alkaloid Luotonin A: Synthesis, computational and biological studies published in 2020.0. Formula: C8H11NO, Reprint Addresses Haider, N (corresponding author), Univ Vienna, Dept Pharmaceut Chem, Althanstr 14, A-1090 Vienna, Austria.. The CAS is 104-10-9. Through research, I have a further understanding and discovery of 2-(4-Aminophenyl)ethanol

A series of new Luotonin A derivatives with substituents at rings A and E was synthesized, together with some E-ring-unsubstituted derivatives. Subsequently, the compound library was examined in silico for their binding into a previously proposed site in the DNA/topoisomerase I binary complex. Whereas no convincing correlation between docking scores and biological data from in vitro assays could be found, one novel 4,9-diamino Luotonin A derivative had strong antiproliferative activity based on massive G2/M phase arrest. As this biological activity clearly differs from the reference compound Camptothecin, this strongly indicates that at least some Luotonin A derivatives may be potent antiproliferative agents, however with a different mode of action.

Product Details of 91-00-9. I found the field of Chemistry very interesting. Saw the article An Improved Class of Phosphite-Oxazoline Ligands for Pd-Catalyzed Allylic Substitution Reactions published in 2019.0, Reprint Addresses Pamies, O; Dieguez, M (corresponding author), Univ Rovira & Virgili, Dept Quim Fis & Inorgan, C Marcel Li Domingo 1, E-43007 Tarragona, Spain.; Norrby, PO (corresponding author), AstraZeneca Gothenburg, R&D BioPharmaceut, Pharmaceut Sci, Data Sci & Modelling, Pepparedsleden 1, S-43150 Molndal, Sweden.; Norrby, PO (corresponding author), Univ Gothenburg, Dept Chem & Mol Biol, Kemigarden 4, S-41296 Gothenburg, Sweden.. The CAS is 91-00-9. Through research, I have a further understanding and discovery of Diphenylmethanamine.

A method for generation of Pd/phosphite-oxazoline catalysts containing an alkyl backbone chain has been successfully applied to Pd-catalyzed allylic substitution reactions. By carefully selecting the substituents at both the alkyl backbone chain and the oxazoline of the ligand, as well as the configuration of the biaryl phosphite group, high activities (TOF > 8000 mol substrate X (mol Pd X h)(-1)) and excellent enantioselectivities (ee’s up to 99%) have been achieved for many hindered and unhindered substrates with a wide range of C-, O-, and N-nucleophiles (73 substitution products in total). Moreover, DFT and NMR studies of the key Pd-allyl complexes allowed us to better understand the origin of the excellent enantioselectivities observed experimentally. The useful application of the Pd/phosphite-oxazoline catalysts was demonstrated by the syntheses of many chiral carbobicycles, with multiples stereocenters, by simple sequential reactions involving Pd-allylic substitution and either 1,6-enyne cyclization or Pauson-Khand enyne cyclization.

A stereoselective amination/cyclization cascade process has been developed that allows for the preparation of a series of unsaturated and substituted caprolactam derivatives in good yields. This conceptually novel protocol takes advantage of the easy access and modular character of vinyl gamma-lactones that can be prepared from simple precursors. Activation of the lactone substrate in the presence of a suitable Pd precursor and newly developed phosphoramidite ligand offers a stereocontrolled ring-opening/allylic amination manifold under ambient conditions. The intermediate (E)-configured epsilon-amino acid can be cyclized using a suitable dehydrating agent in an efficient one-pot, two-step sequence. This overall highly chemo-, stereo- and regio-selective transformation streamlines the production of a wide variety of modifiable and valuable caprolactam building blocks in an operationally attractive way.

Nucleophilic substitutions of benzylic alcohols with sulfamides were achieved using an FeCl3 Lewis acid catalyst in MeNO2. It was necessary to adjust the reaction conditions to obtain efficient yields depending on the stability of the carbocation intermediates. The reaction could easily be performed, and it was revealed that a variety of diarylmethanols and benzylic alcohols were applicable to the reaction, irrespective of the type and position of the substituents. The sulfamide moieties were easily deprotected and converted into amine groups.

The indolylmaleimide (IM) derivative IM-17 shows inhibitory activity against oxidative-stress-induced necrotic cell death and cardioprotective activity in rat ischemia-reperfusion injury models. In order to develop a more potent derivative, we conducted a detailed structure-activity relationship study of IM derivatives and identified IM 93 as the most potent derivative with good water solubility. IM-93 inhibited ferroptosis and NETosis, but not necroptosis or pyroptosis. In contrast, ferrostatin-1 (Fer-1), a ferroptosis inhibitor, did not inhibit NETosis, although the accompanying lipid peroxidation was partially inhibited by Fer-1, as well as by IM-93. Thus, IM derivatives have a unique activity profile and appear to be promising candidates for in vivo application.

Category: amides-buliding-blocks. I found the field of Biochemistry & Molecular Biology; Chemistry very interesting. Saw the article Synthesis of 3-indolylmethyl substituted (pyrazolo/benzo)triazinone derivatives under Pd/Cu-catalysis: Identification of potent inhibitors of chorismate mutase (CM) published in 2019, Reprint Addresses Pal, M (corresponding author), Dr Reddys Inst Life Sci, Univ Hyderabad Campus, Hyderabad 500046, India.. The CAS is 90-16-4. Through research, I have a further understanding and discovery of Benzo[d][1,2,3]triazin-4(3H)-one.

The chorismate mutase (CM) is considered as an attractive target for the identification of potential antitubercular agents due to its absence in animals but not in bacteria. A series of 3-indolylmethyl substituted pyrazolo-triazinone derivatives were designed and docked into CM in silico as potential inhibitors. These compounds were efficiently synthesized using the Pd/Cu-catalyzed coupling-cyclization in a single pot involving the construction of indole ring. The methodology was later extended to the preparation of corresponding benzo analogs of pyrazolotriazinones i.e. 3-indolylmethyl substituted benzotriazinone derivatives. Several of these novel compounds showed significant inhibition of CM when tested in vitro at 30 mu M. The SAR (Structure-Activity-Relationship) studies suggested that benzotriazinone moiety was more favorable over the pyrazolotriazinone ring. The two best active compounds showed IC50 similar to 0.4-0.9 mu M (better than the reference/known compounds used) and no toxicity till 30 mu M in vitro.

It is a persistent target to develop noble-metal-free catalysts that can achieve chemoselective hydrogenation of nitro compounds under mild reaction conditions. In this work, we report a new strategy for preparation of hydrogenation catalysts containing both CoNx and CoyZnS supported on N-doped porous carbon (CoNx-CoyZnS@NPC-Z). The CoNx-CoyZnS@NPC-Z catalysts were prepared by pyrolyzing the protein-metal-ion networks, followed by treatment with acid. We found that CoNxCoyZnS@NPC-3 catalyst delivers high catalytic activity and selectivity, affording almost full conversion and >98% selectivity in water/methanol mixture solvents at 90 degrees C under 5 bar of H-2 pressure for 3 h of reaction. Notably, the catalytic hydrogenation can work even under 1 bar of H-2 pressure and at room temperature with high conversion and selectivity. Besides, CoNx-CoyZnS@NPC-3 exhibits remarkable tolerance to CO or H2S poisoning and acid erosion.
