Preclinical studies of a new octreotide derivative with a chelate (DPAH-octreotide) that binds 99mTc for radiological diagnosis of neuroendocrine tumors are currently in progress. A method for preparing DPAH-octreotide is based on forming an amide bond between the amine of D-phenylalanine and the bifunctional chelate succinimid-1-yl 6-[bis(pyridin-2-ylmethyl)amino]hexanoate. An HPLC method for determining the identity, impurities, and quantitative content is proposed for DPAH-octreotide quality assurance. The validation protocol established that the HPLC analytical method for determining DPAH-octreotide had quality parameters for specificity, detection limit, linearity, accuracy, precision, and intralaboratory precision that met requirements for analytical methods and could be used for quality control of the finished product during manufacturing of reagents for preparation of related radiopharmaceuticals.

Structural variations of the benzylphenoxyacetamide (BPA) molecular skeleton were explored as a viable starting point for designing new anti-glioblastoma drug candidates. Hand-to-hand computational evaluation, chemical modifications, and cell viability testing were performed to explore the importance of some of the structural properties in order to generate, retain, and improve desired anti-glioblastoma characteristics. It was demonstrated that several structural features are required to retain the anti-glioblastoma activity, including a carbonyl group of the benzophenone moiety, as well as 4′-chloro and 2,2-dimethy substituents. In addition, the structure of the amide moiety can be modified in such a way that desirable anti-glioblastoma and physical properties can be improved. Via these structural modifications, more than 50 compounds were prepared and tested for anti-glioblastoma activity. Four compounds were identified (HR28, HR32, HR37, and HR46) that in addition to HR40 (PP1) from our previous study, have been determined to have desirable physical and biological properties. These include high glioblastoma cytotoxicity at low mu M concentrations, improved water solubility, and the ability to penetrate the blood brain barrier (BBB), which indicate a potential for becoming a new class of anti-glioblastoma drugs.

For small molecule reaction kinetics, computed reaction coordinates often mimic experimentally measured observables quite accurately. Although nowadays simulated and measured biomolecule kinetics can be compared on the same time scale, a gap between computed and experimental observables remains. Here we directly compared temperature-jump experiments and molecular dynamics simulations of protein folding dynamics using the same observable: the time-dependent infrared spectrum. We first measured the stability and folding kinetics of the fastest-folding -protein, the GTT35 WW domain, using its structurally specific infrared spectrum. The relaxation dynamics of the peptide backbone, -sheets, turn, and random coil were measured independently by probing the amide I region at different frequencies. Next, the amide I spectra along folding/unfolding molecular dynamics trajectories were simulated by accurate mixed quantum/classical calculations. The simulated time dependence and spectral amplitudes at the exact experimental probe frequencies provided relaxation and folding rates in agreement with experimental observations. The calculations validated by experiment yield direct structural evidence for a rate-limiting reaction step where an intermediate state with either the first or second hairpin is formed. We show how folding switches from a more homogeneous (apparent two-state) process at high temperature to a more heterogeneous process at low temperature, where different parts of the WW domain fold at different rates.

There are several differentiation methods for mesenchymal stem cells (MSCs) into hepatocyte-like cell. Investigators reported various hepatic differentiation protocols such as modifying culturing conditions or using various growth factors/cytokines. In this literature review, we compared different MSCs extraction and isolation protocols from Wharton’s jelly (WJ) and explored various MSCs differentiation methods. Various protocols have been recommended for MSCs isolated from WJ, such as enzymatic, enzymatic-explant, and explant methods. In the explant method, valuable time is wasted, but the cost and biological contaminations are reduced and the number of isolated cells is high. However, other features, such as immune phenotype and multiline-age differentiation capacity, do not differ from other methods. There are also several differentiation methods for hepatocyte-like cell including the induction of MSC by cytokines and growth factors, and the differentiation of MSC in 2- and 3-dimensional matrix (2D and 3D). Among several cytokines, hepatocyte growth factor (HGF) and fibroblast growth factor (FGF) are essential. In the early stage of the differentiation, 2D culture is useful, and in the development stage, 3D culture system with HGF and FGF cytokines are more effective in the process of differentiation. Some studies have used 3D culture system in biocompatible scaffolds, such as alginate, collagen, gelatin, and peptide-Gly-Leu-amide (PGLA). In conclusion, Wharton’s jelly-Mesenchymal stem cells (WJ-MSCs) can be considered as an appropriate source for hepatocyte differentiation. Moreover, we introduced the explant method as the most effective protocol. This review attempted to highlight factors in hepatocyte differentiation, but the most effective protocol is not still unknown.

A ruthenium-catalyzed highly selective difluoromethylation of 8-aminoquinoline amides at the C5 position has been developed. It tolerates a broad range of functional groups, providing the corresponding difluoromethylated products in moderate to good yields. Preliminary experimental results indicate that the tricoordinate ruthenium intermediate is the key factor in achieving the C5-position selectivity.

Scaffold hopping from the amide group of lead compound ONO 7300243 (1) to a secondary alcohol successfully gave a novel chemotype lysophosphatidic acid receptor 1 (LPA(1)) antagonist 4. Wash-out experiments using rat isolated urethra showed that compound 4 possesses a tight binding feature to the LPAI receptor. Further modification of two phenyl groups of 1 to pyrrole and an indane moiety afforded an optimized compound ONO-0300302 (19). Despite its high i.v. clearance, 19 inhibited significantly an LPA-induced increase of intraurethral pressure (IUP) in rat (3 mg/kg, p.o.) and dog (1 mg/kg, p.o.) over 12 h. Binding experiments with [H-3]-ONO-0300302 suggest that the observed long duration action is because of the slow tight binding character of 19.

Although the aldol condensation is a well-known reaction, the aza-type aldol condensation, namely, the intramolecular condensation of common keto lactams leading to bicyclic vinylogous lactams, is a highly demanding transformation, with potential applications in both organic synthesis and medicinal chemistry. The known methods for this type of cyclization require several steps. In this paper, we disclose a straightforward approach that consists of the in-situ formation of silyl enol ethers with tert-butyldimethylsilyl trifluoromethanesulfonate (TBDMSOTf), lactam activation with triflic anhydride (Tf2O), and a tandem cyclocondensation reaction. The reaction can be run in a one-pot manner or in a two-step fashion, both under mild conditions. The yields for the one-pot version were 52-80%. In some cases, the two-step version gave higher overall yields (44-85%) than the one-pot version.

The implementation of a future economy based on hydrogen-related energy needs an urgent development of efficient, safe, and economic solid-state hydrogen-storage materials. During the search process for novel materials for storing hydrogen, research interests in the past few decades have been intensively focused on light metal borohydrides and amides as two representative chemical complex hydrides with high hydrogen capacities. Recently, a large number of studies have reported new borohydride/amide combined systems that expand the scope of hydrogen-storage materials. Here, we review the interaction between light metal borohydrides and amides for storing hydrogen, with a special emphasis on the synthetic strategies and structural, physical, and chemical properties, which reveal a correlation between the composition, structure, and dehydrogenation properties and also provide general principles to the design of new combined systems with tailored functionality. This review also demonstrates the current progress on the dehydrogenation kinetic improvement of borohydride/amide combined systems.
