- Antiproliferative and antibacterial activity of some glutarimide derivatives
-
Antiproliferative and antibacterial activities of nine glutarimide derivatives (1–9) were reported. Cytotoxicity of compounds was tested toward three human cancer cell lines, HeLa, K562 and MDA-MB-453 by MTT assay. Compound 7 (2-benzyl-2-azaspiro[5.11]heptadecane-1,3,7-trione), containing 12-membered ketone ring, was found to be the most potent toward all tested cell lines (IC50 = 9–27 μM). Preliminary screening of antibacterial activity by a disk diffusion method showed that Gram-positive bacteria were more susceptible to the tested compounds than Gram-negative bacteria. Minimum inhibitory concentration (MIC) determined by a broth microdilution method confirmed that compounds 1, 2, 4, 6–8 and 9 inhibited the growth of all tested Gram-positive and some of the Gram-negative bacteria. The best antibacterial potential was achieved with compound 9 (ethyl 4-(1-benzyl-2,6-dioxopiperidin-3-yl)butanoate) against Bacillus cereus (MIC 0.625 mg/mL; 1.97 × 10?3mol/L). Distinction between more and less active/inactive compounds was assessed from the pharmacophoric patterns obtained by molecular interaction fields.

- Synthesis of 4-substituted 3,5-dicyano-2,6-piperidinediones using lithium nitride as a convenient source of ammonia
-
A simple and efficient one-pot synthesis of 4-substituted-3,5-dicyano-2,6-piperidinediones was achieved in good yields via the three-component reaction of aldehyde or ketone, ethyl cyanoacetate, lithium nitride (Li3N) as a convenient source of ammonia in MeOH.
