Novel rhodanine derivatives induce growth inhibition followed by apoptosis

We have designed and synthesized three novel compounds, 5-isopropylidiene derivatives of 3-dimethyl-2-thio-hydantoin (ITH-1), 3-ethyl-2-thio-2,4- oxazolidinedione (ITO-1), and 5-benzilidene-3-ethyl rhodanine (BTR-1), and have tested their chemotherapeutic properties. Our results showed that all three compounds induced cytotoxicity in a time- and concentration-dependent manner on leukemic cell line, CEM. Among the compounds tested, BTR-1 was 5- to 7-fold more potent than ITH-1 and ITO-1 when compared by trypan blue and MTT assays. IC50 value of BTR-1 was estimated to be <10 muM. Both cell cycle analysis and tritiated thymidine assays revealed that BTR-1 affects DNA replication by inducing a block at S phase. BTR-1 treatment led to increased level of ROS production and DNA strand breaks suggesting activation of apoptosis for induction of cell death.

Synthesis and antimicrobial activity evaluation of the pyrrole-derived heterocycles bearing two functionalities

Background: The pyrrole ring is widely spread and incorporated into the structures of many naturally occurring compounds e.g. heme, chlorophyll, vitamin B12 and the bile pigments. Pyrrolnitrin and pyoluteorin are naturally occurring pyrroles which have antibiotic activity, and the methyl ester of 4-methylpyrrole-2-carboxylic acid is an insect pheromone. Moreover, the highly successful cholesterol lowering drug Lipitor is a poly substituted pyrrole derivative. Methods: Some novel pyrrole derivatives bearing other heterocyclic rings at positions-2 and -3 were synthesized and their antimicrobial activities were studied. Results: A series of novel pyrrolinthione, thiazolidinone, thiazolone, tetrazole, sulphonamides derivatives have been synthesized through a facile strategy and screened for antimicrobial activities, some of the prepared compounds exhibited high antibacterial and antifungal activities compared with the standard drugs. Conclusion: These compounds provided the impetus for most of the early work on the synthesis and reactions of pyrroles and still a very active of research. Many such explorations are anticipated in near future.

Synthesis of bis-dibenzonaphthyridines and evaluation of their antibacterial activity

Reaction of phthalic acid with 2-methyl-4-N-phenylaminoquinoline under PPA condition resulted in the formation of 6-methyldibenzo[b, h][1,6]naphthyridines, whereas the same reaction with 2,4-bis(N-phenylamino)quinoline resulted in the dimeric dibenzo[b, h][1,6]naphthyridines. A novel mechanism has been proposed to explain the formation of the unexpected product. Screening for the antibacterial activity against various pathogens, proved that the dimeric analogs showed a better antibacterial activity when compared to their monomeric analogs.

Quantum chemical calculations and molecular docking studies of 5-(4-chlorobenzylidene)thiazolidine-2,4-dione(CTD) and its mannich product 5-(4-chlorobenzylidene)-3-(morpholinomethyl)thiazolidine-2,4-dione (CMTD)

This work presents the synthesis of 5-(4-chlorobenzylidene)thiazolidine-2,4-dione (CTD) by Claisen condensation of thiazolidine-2,4-dione and mannich product of CTD, 5-(4-chlorobenzylidene)-3-(morpholinomethyl)thiazolidine-2,4-dione (CMTD). The static first hyperpolarizability values for thiazolidine-2,4-dione derivatives have been calculated as 10.28 × 10?30 esu for CTD and 19.42 × 10?30 esu for CMTD. The gradual increase in hyperpolarizability values of synthesized thiazolidine-2,4-dione derivatives from CTD to CMTD is due to the blockage of [sbnd]NH group on CTD by mannich reaction. The structures of these compounds have been derived by spectroscopic(IR, UV, Mass, 1H and 13C NMR) analysis as well as with the help of theoretical studies. The high values of first static hyperpolarizability indicate that the synthesized derivatives are suitable as non?linear optical (NLO) material. CTD with MIC value of 12.5 mug/mL can be developed as an alternative drug for the treatment of enteric fever. Calculated frontier orbital gap values suggest that the CMTD is a soft molecule with high chemical reactivity and is more polarizable as compared to the CTD. Molecular electrostatic potential is calculated for the optimized geometry of the molecules to estimate their chemical reactivity. The inhibitor CTD forms a stable complex with 3-dehydroquinase enzyme of Salmonella typhi. It is evident from the ligand receptor interactions and a binding affinity value of ?5.88 kcal/mol and an inhibition constant of 49.22 muM. This is further confirmed by the experimental biological data. The molecular docking studies are supportive of the antibacterial activity of CTD exhibiting high inhibition constant and binding energy.
