A series of di-substituted cinnamic hydroxamic derivatives was designed, synthesized and evaluated as HDAC inhibitors. Compound 5f (HS270) demonstrated potent HDAC inhibitory and antiproliferative activities. In xenograft model, 5f showed significant antitumor efficacy in tumorbearing mice.

Structure and ligand based approaches are effectively employed for the accurate design of ligands. The main objective of this study was to find out the correlation between structure and biological activity using structure and ligand based methodology. Azetidin-2-ones have been recognized as effective tubulin polymerization inhibitors that bind to the colchicine site on β-tubulin. Molecular docking (structure based method) was p Read More

A series of 7,8-dihydroxy-4-arylcoumarins, the derivatives related to DW532 that was an anti-tumor agent targeting both kinase and tubulin, was prepared by Suzuki coupling reaction. Among them, compounds 6a, 6b, and 6c were found to exhibit anti-proliferation activities against human breast carcinoma MDA-MB-468 cells with IC50 values of 0.64, 0.69, and 1.33 μM, respectively and human epidermoid carcinoma A431 c Read More

Naphthalimide-benzimidazole conjugates were prepared using two different types of spacer units; either a simple alkane chain or a substituted piperazine moiety with variable alkyl side chains. Each set of conjugates was evaluated for their in vitro anticancer activity, and compounds 14a, 14b and 20c were found to exhibit significant activity against a number of cancer cell lines. In particular, compound 14a showed remark Read More

18 chromone derivatives were designed and synthesized from paeonol. All synthetic compounds were evaluated for their anti-proliferative activity towards eight human cancer cell lines including HepG2, HL-60, KB, LLC, LNCaP, LU-1, MCF7, and SW480. Compounds 3g and 3h presented the best cytotoxic effects towards tested cancer cell lines except HepG2. Their IC50 values were ranging from 7.9±0.4 to 18.9±1.3 μg/mL. Mean Read More

A series of novel fluorinated heterocyclic hybrid molecules based on triazole & quinoxaline scaffold were designed, synthesized and evaluated for inhibition of Plasmodium falciparum, a virulent human malaria parasite. Mono and bis triazole tagged quinoxaline analogs were synthesized by propargylation of 6-amino quinoxaline followed by click reaction with various substituted aromatic azides under uncertain reaction condi Read More

Thirteen α-aminophosphonate derivatives with artesunate were synthesized by introducing bioactive α-aminophosphonate combination with artesunate in this work. The reaction were easily carried out at normal pressure, low temperature and without any catalyst. Four strains of microbials, namely Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans, were used for the evaluati Read More

The heterocyclic system is a promising core nucleus in many bioactive compounds. This work describes our effort to synthesize and characterize a set of new biphenyl, benzofuran and benzothiophene carboxamide derivatives. Our biological studies showed that compounds 10 and 17 have antifungal activity against C. galabrate more potent than fluconazole compounds 9, 10, and 17 exerted cytotoxic activities in immortaliz Read More

The present study involved the design and synthesis of new substituted 4-[2-(4- alkoxybenzylamino) ethyl]-2H-1,2,4-triazol-3(4H)-one derivatives (8a-w) starting from 1,2- ethanediamine. The final compounds were screened for their in vivo anticonvulsant activities and neurotoxicities by maximal electroshock (MES) and rotarod tests, respectively. Among the compounds studied, 4-[2-(4-butoxybenzylamino)ethyl]-2H-1,2,4- Read More

Neonicotinoids are the most widely used insecticides currently, but their nematicidal activity was seldom reported. A series of spiro or bridged heterocyclic neonicotinoid analoges was prepared and their nematicidal activity was evaluated. Most of the synthesized compounds showed moderate to good nematicidal activity against Meloidogyne incognita. The investigations here provide the novel nematicidal chemotypes Read More
