Ru-catalyzed alkylation of 3-formylbenzofuran with acrylates and acrylamides has been described. Branched selectivity with unsubstituted or beta-substituted acrylates/acrylamides and linear selectivity with alpha-substituted acrylates have been observed. However, in all of the cases, the intermediate alkylation products seem to undergo further reactions, either cycloannulation or deformylation, depending on the substrate employed. For example, with methyl acrylate, the intermediate branched alkylation product underwent cycloannulation with another molecule of methyl acrylate, resulting in a densely functionalized cyclohexene ring formation. On the other hand, in the case of N-monosubstituted acrylamides, the branched alkylation proceeded with intramolecular aldehyde-amide condensation, leading to pyridin-2-one ring annulation. However, with both methacrylate and crotonate, deformylation of the initially formed alkylation products was observed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Reference of 19012-03-4, you can also check out more blogs about19012-03-4

For the purpose of obtaining orally potent VLA-4 inhibitors, we have carried out structural modification of the (N?-phenylureido)phenyl group in compound 1, where the group was found to be attributed to poor pharmacokinetic profile in our previous research. Through modification, we have identified several compounds with both potent in vitro activity and improved oral exposure. In particular, compound 7e with 7-fluoro-2-(1-methyl-1H-indol-3- yl)-1,3-benzoxazolyl group as a novel replacement of the (N?-phenylureido) phenyl group significantly inhibited eosinophil infiltration into bronchoalveolar lavage fluid at 15 mg/kg in an Ascaris-antigen-induced murine bronchial inflammatory model, and its efficacy was comparable to that of the anti-mouse alpha4 antibody (R1-2).

In connection with our research program on the development of novel anti-tubercular candidates, herein we report the design and synthesis of two different sets of indole-thiazolidinone conjugates (8a,b; 11a-d) and (14a-k; 15a-h). The target compounds were evaluated for their in vitro antibacterial and antifungal activities against selected human pathogens viz. Staphylococcus aureus (Gram positiveve), Pseudomonas aeruginosa, Escherichia coli (Gram negative), Mycobacterium tuberculosis (Acid-fast bacteria), Aspergillus fumigates and Candida albicans (fungi). Moreover, eukaryotic cell-toxicity was tested via an integrated ex vivo drug screening model in order to evaluate the selective therapeutic index (SI) towards antimicrobial activity when microbes are growing inside primary immune cells. Also, the cytotoxicity towards a panel of cancer cell lines and human lung fibroblast normal cell line, WI-38 cells, was explored to assure their safety. Compound 15b emerged as a hit in this study with potent broad spectrum antibacterial (MIC: 0.39?0.98 mug/mL) and antifungal (MIC: 0.49?0.98 mug/mL) activities, in addition to its ability to kill mycobacteria M. aurum inside an infected macrophage model with good therapeutic window. Moreover, compound 15b displayed promising activity towards resistant bacteria strains MRSA and VRE with MIC values equal 3.90 and 7.81 mug/mL, respectively. These results suggest compound 15b as a new therapeutic lead with good selectivity for further optimization and development.

The enolate of 4-N-(tert-butyloxycarbonyl)aminobutyro-gamma-lactone 9 reacted with 2-bromo-1methylindole-3-carboxaldehyde in the presence of stannic chloride to give the product of aldol condensation 16. Deprotection and dehydration of the latter with trifluoroacetic acid and dimethyl sulfide followed by Pd2(dba)3 -catalyzed ring closing of the product afforded the alpha-carboline 6 in good overall yield.

C-H functionalization of electron-deficient heteroarenes using commercial unactivated alkyl halides through reductive quenching photoredox catalysis was developed. Mainstream approaches rely on the use of an excess of strong acids that result in regioselectivities dictated by the innate effect of the protonated heteroarene, leaving the functionalization of other carbons unexplored. We report a mild method under basic conditions that allows access to previously underexplored regioselectivities by relying on a combination of conjugate and halogen ortho-directing effects. Overall, this methodology gives quick access to a variety of alkylated heteroarenes that will be of interest to medicinal chemistry programs.

A diverse series of 22 indolyl-1,2,4-triazole congeners (6 and 7) have been synthesized from the reaction of indole-3-carbonitrile (4) or (5) with appropriate acid hydrazides in the presence of potassium carbonate. Synthesized compounds were evaluated for their cytotoxicity against six human cancer cell lines, and some of the compounds displayed promising activity. In particular, 3-(3′,4′,5′-trimethoxyphenyl)-5-(N-methyl-3′-indolyl)-1,2,4-triazole (7i) and 3-(4′-piperidinyl)-5-(N-methyl-3′-indolyl)-1,2,4-triazole (7n) were the most promising and broadly active compounds against the tested cell lines. It was interesting to note that the trimethoxyphenyl analog 7i showed twofold selective cytotoxicity against PaCa2 cell line (IC50 0.8mum), whereas piperidinyl analog 7n was found to be selectively cytotoxic against MCF7 cell line (IC50 1.6mum). Notably, the 4-fluorophenyl derivative 7c exhibited selective cytotoxicity against PC3 cell line (IC50 4mum). The structure-activity relationship study revealed that substituents including 3,4,5-trimethoxyphenyl, 3,4-dimethoxyphenyl, 4-benzyloxy-3-methoxyphenyl, 4-piperidinyl, 4-fluorophenyl and N-methylindole are beneficial for the activity of indolyl-1,2,4-triazoles (6 and 7).
