Cross-dehydrogenative coupling of biorelevant heterocyclic scaffolds with arylmethanes for aroylation during Pd(II)-catalyzed C(sp2)-H activation has been achieved through dioxygen activation by NHPI. Mass spectrometry and 1H NMR based kinetic isotope effect studies revealed C-H bond activation as the rate-determining step. Radical scavenging experiments indicated a radical pathway. The 1H NMR of an aliquot of reaction mixture and in situ trapping with 2-aminothiophenol revealed the formation of aldehyde during aerobic oxidation of the arylmethanes. The reaction has broad scope for different variations of the aroyl source and the directing group that includes benzothiazole, benzooxazole, pyridine, quinoxaline, pyrimidine, and azoarene. The benzylic methylene moiety was found to be the source of the aroyl carbon with the benzyl ether moiety being the most preferred followed by the carbonyl group of aryl aldehyde and the aryl methane. However, the ease of availability of aryl methanes makes them the most attractive as an aroyl source. A time dependent selective mono- and bis-aroylation can be achieved. The 1,3-diarylpyrimidines exhibited regioselective aroylation of the 2-phenyl moiety irrespective of the absence or presence of any substitutent (electron withdrawing or electron donating) in the 3-phenyl moiety. For unsymmetrical azoarenes, selective aroylation took place in the phenyl moiety bearing the substituent.

Aims and Objective: The magic scaffolds rhodanine and thiazolidine are very important heterocyclic compounds in drug design and discovery. Those are important heterocyclic compounds that have attracted a great deal of attention due to the fact that they exhibit a variety of bioactivities including antibacterial, antifungal, antiviral, antimalarial, and anti-inflammatory activities. These agents often exhibit selective toxicity. The goal of this study was molecular docking, green and solvent-free efficient synthesis of a new series of hetero/aromatic substituted rhodanine and thiazolidine analogues and then investigation of their antimicrobial activity. Materials and Methods: To a mixture of TZD or rhodanine (1 mmol) in the presence of ionic liquid ChCl/urea, various aldehyde (1 mmol) was added. After completion of the reaction, obtained crude compound was collected by filtration and products were recrystallized from ethanol. The binding-free energy between all synthesized compounds with 3EEJ protein (C. glabrata enzyme) were obtained by molecular docking studies. These compounds were evaluated using microdilution method against (ATCC 6538) and (ATCC 12228) Gram-negative, (ATCC 8739) and (ATCC 9027) as Gram-positive and (ATCC 1012), (ATCC 339), C. (ATCC 1057), (ATCC 503), (ATCC 340) and (ATCC 194) as fungi. Results: All of the acceptable products were determined by1H NMR,13C NMR, Mas and FT-IR spectroscopy. The binding-free energy between compounds 10a and 10b with 3EEJ protein were found to be-8.08 kcal/mol and-8.15 kcal/mol, respectively. These compounds having a heteroaromatic ring attached to the TZD or rhodanine core showed excellent antimicrobial activity with MIC values of 0.25-8 mug/mL (compound 10a) and 0.5-16 mug/mL (compound 10b) against the most tested fungi strains, Gram-positive and Gram-negative bacteria. Conclusion: A convenient and rapid method has been developed for the synthesis of rhodanine and thiazolidine-2,4-dione (TZD) derivatives as efficient antimicrobial agents using a Deep Eutectic Ionic Liquids (DEILs) choline chloride urea under solvent-free condition. Among the newly synthesized compounds, (Z)-5-((quinoxalin-3-yl) methylene) thiazolidine-2, 4-dione (10a) and (Z)-5-((quinoxalin-3-yl) methylene)-2-thioxothiazolidin-one (10b) exerted the promising effect and these compounds can be considered to be further probed as inhibitors of cgDHFR enzyme.

Application of 1603-91-4, An article , which mentions 1603-91-4, molecular formula is C4H6N2S. The compound – 4-Methylthiazol-2-amine played an important role in people’s production and life.

Four new complexes of Ru(III) with a general formula [Ru(L) 2Cl2]Cl, where L = 2-amino-4-phenylthiazole (CAS 2010-06-2), 2-amino-4-methylthiazole (CAS 1603-91-4), ethyl 2-amino-4-methyl-5- thiazole-carboxylate (CAS 7210-76-6) and ethyl 2-amino-4-phenyl-5- thiazolecarboxylate (CAS 64399-23-1), were prepared. The syntheses were carried out in polar medium and inert atmosphere at a molar ratio Ru:L = 1:2 or 1:3. The compounds obtained were characterised by IR-, 1H-NMR- 13C-NMR-, UV-VIS-, EPR spectroscopy, magnetochemical and conductivity measurements. The ligands behaved as bidental, bounding Ru(III) through the nitrogen atoms from the amino group and the heterocycle. The complex of ethyl 2-amino-4-phenyl-5-thiazolecarboxylate showed significant antileukaemic activity on various human cells (IC50 values ranging from 20 to 92 mumol/l). Toxicological studies on mice indicated that such concentrations could be reached without mortality. This compound exhibited a promising antineoplastic potential and needs further pharmacological and toxicological evaluation.

We here report the synthesis and biological evaluation of an original collection of 4,7-disubstituted pyrido[3,2-d]pyrimidines designed as potential kinase inhibitors. The collection was generated from a single starting material, 4,7-dichloropyrido[3,2-d]pyrimidine, which afforded the final compounds after two steps: a sequential or one-pot sequence including selective cross coupling reactions in C-4, followed by the second cross-coupling in C-7. In position C-4, a Suzuki-Miyaura type reaction led to monosubstituted derivatives whereas in position C-7, synthesis was achieved via a Suzuki or a Buchwald type reaction using commercially available or undescribed boron derivatives. The biological activity of the V-shaped family was measured in protein kinase assays. The structure activity relationship (SAR) revealed that some compounds selectively inhibited DYRK1A and CDK5 without affecting GSK3. Docking studies furnished possible explanations that correlate with the SAR data. The most active compound on the two biological targets was 27 which exhibited the following IC 50: 110 nM for CDK5, 24 nM for DYRK1A and only 1.2 muM for GSK3. In the C-7 amino subfamily, the best derivative was indubitably compound 48 which led to a near selective action on DYRK1A and a remarkable IC50 of 60 nM.

In this paper, we applied a chemotype-assembly approach for ligand-based drug discovery (LBDD) to discover novel anti-osteoporosis leads. With this new approach, we identified 12 chemotypes and derived 18 major chemotype assembly rules from 245 known anti-osteoporosis compounds. Then, we selected 19 compounds from an in-house compound library using chemotype-assembly approach for anti-osteoporosis assays, which resulted in 13 hits. Based on structural features in these 13 compounds, we synthesized 50 possible anti-osteoporosis compounds from the anti-osteoporosis chemotypes by means of click chemistry techniques and discovered a compound (10a, IC50 = 2 nM) with nanomolar activity. Compound 10a was then proved to be an anti-osteoporosis lead since it can prevent bone loss in vivo.
