A series of spirochromene-tethered 1,2,3-triazoles (1,2,3-triazolylspirochromenes) were designed and synthesized via click-chemistry-based one-pot five-component reaction between N-propargyl isatins, malononitrile, dimedone (or 4-hydroxyl-6-methyl-2H-pyran-2-one), arylalkyl halides, and sodium azide using cellulose-supported CuI nanoparticles (Cell-CuI NPs) as heterogeneous catalyst. All synthesized compounds were screened for inhibitory activity against Mycobacterium tuberculosis H37Ra (ATCC 25177) and Mycobacterium bovis BCG (ATCC 35743), in active as well as dormant state. During screening, compounds 6h, j, l were found to exhibit promising antimycobacterial activity against M.?bovis BCG, while compounds 7d, h, l showed promising antimycobacterial activity against M.?tuberculosis H37Ra as well as M.?bovis BCG. The active compounds were found to be noncytotoxic to three human cancer cell lines (MCF-7, HCT116, and A549). The active compounds exhibited selectivity index >10, indicating potential as antitubercular agents. The active compounds were also evaluated for in?vitro antibacterial activity, with five (6h, l, 7b, f, l) showing good antibacterial activity against Gram-positive as well as Gram-negative bacteria. Compounds 6h, j, l exhibiting promising activity against M.?bovis BCG can serve as good leads for further modification and optimization.

Molecular hybridization is a valuable approach in drug discovery. Combining it with multicomponent reactions is highly desirable, since structurally diverse libraries can be attained efficiently in an eco-friendly manner. In this work, isatin is used as the key building block for the Ugi 4-center 3-component reaction synthesis of oxindole-lactam hybrids, under catalyst-free conditions. The resulting oxindole-β-lactam and oxindole-γ-lactam hybrids were evaluated for their potential to inhibit relevant central nervous system targets, namely cholinesterases and monoamine oxidases. Druglikeness evaluation was also performed, and compounds 4eca and 5dab exhibited great potential as selective butyrylcholinesterase inhibitors, at the low micromolar range, with an interesting predictive pharmacokinetic profile. Our findings herein reported suggest oxindole-lactam hybrids as new potential agents for the treatment of Alzheimer's disease.

We report herein the design, synthesis, and in vitro anti-tumor activities of a series of 1,2,3-triazole-tetraethylene glycol tethered heteronuclear bis-Schiff base derivatives of isatin. Our results indicated that all the synthesized bis-Schiff bases except 9e showed considerable in vitro anticancer activities against HepG2, Hela, HCT-116, A549, and MCF-7 human cancer cell lines with IC50 in a range of 9.79–48.75?μM and were more potent than etoposide against Hela, HCT-116, and A549 cell lines. In particular, the most potent bis-Schiff base 9g (IC50: 9.79–29.64?μg/mL) was highly active against the five cancer cell lines tested, could act as a lead for further optimization.

In our search for novel bioactive molecules, three series of indolin-2-one derivatives incorporating 1-benzyl-1H-1,2,3-triazole moiety were synthesized. The compounds were initially designed as acetylcholine esterase (AChE) inhibitors based on the structu

A small library of 36 new glycohybrids of phenylhydrazono-indolinones was synthesized employing glycosylated 1,2,3-triazolyl-methyl-indoline-2,3-diones and different phenylhydrazines via acid catalyzed reaction. All the compounds were screened for their antiplasmodial activity in vitro. Compounds 6c, 7c, and 7b showed significant activity with the IC50 values 1.27, 1.64 and 1.96 μM, respectively against CQ sensitive Pf3D7 strain while compounds 7b and 6f showed good activity with IC50 1.61 and 1.93 μM, respectively against CQ resistant PfK1 strain.

Abstract: A series of seventeen novel hydroxamic acids incorporating 1-((1H-1,2,3-triazol-4-yl)methyl)-3-hydroxyimino-indolin-2-ones was designed and synthesized. Biological evaluation showed that these hydroxamic acids potently inhibited a class-I isoform of HDACs (HDAC2) with IC 50 values in low micromolar range. Several compounds also exhibited good cytotoxicity. Two compounds, 5e and 5f, emerged as the most potent HDAC2 inhibitors with cytotoxicity up to 8-fold more potent than SAHA in three human cancer cell lines, including SW620 (colon cancer), PC3 (prostate cancer) and AsPC-1 (pancreatic cancer). A molecular modeling approach has been carried out which revealed some structure-activity relationships. Further investigation on absorption, distribution, metabolism, excretion and toxicity (ADMET) suggested that compounds 5e and 5f, while showing potent HDAC2 inhibitory bioactivity, hold desirable characteristics for anticancer compounds. GRAPHICAL ABSTRACT: Three series of novel hydroxamic acids incorporating 1-((1H-1,2,3-triazol-4-yl)methyl)-3-hydroxyimino-indolin-2-ones (4a-c, 5a-g, 6a-g) were synthesized. Biological evaluation showed that these hydroxamic acids potently inhibited HDAC2 with IC 50 values in low micromolar range.

The base-induced propargylation of the dye indigo results in the rapid and unprecedented one-pot synthesis of highly functionalized representatives of the pyrazino[1,2-a:4,3-a′]diindole, pyrido[1,2-a:3,4-b′]diindole and benzo[b]indolo[1,2-h]naphthyridine heterocyclic systems, with the last two reflecting the core skeleton of the anticancer/antiplasmodial marine natural products fascaplysin and homofascaplysins and a ring B-homologue, respectively. The polycyclic compounds 6-8, whose structures were confirmed through single-crystal X-ray crystallographic analysis, arise from sequential inter/intramolecular substitution-addition reactions, and in some cases, ring rearrangement reactions. Preliminary studies on controlling the reaction path selectivity, and the potential reaction mechanisms, are also described. Initial biological activity studies with these new heterocyclic derivatives indicated promising in vitro antiplasmodial activity as well as good anticancer activity. The chemistry described is new for the indigo moiety and cascade reactions from this readily available and cheap starting material should be more broadly applicable in the synthesis of additional new heterocyclic systems difficult to access by other means.
