Synthesis and Biological Evaluation of a Series of New Hybrid Amide Derivatives of Triazole and Thiazolidine-2,4-dione.

A series of hybrid compounds with triazole and thiazolidine nuclei connected by a linker has been synthesized and extensively studied. Various synthetic methods for the target compounds have been tested. A microbiological assessment of the obtained compounds was carried out on strains of pathogenic fungi , , multidrug-resistant , , spp.

Antifungal Thiazolidines: Synthesis and Biological Evaluation of Mycosidine Congeners.

Novel derivatives of Mycosidine (3,5-substituted thiazolidine-2,4-diones) are synthesized by Knoevenagel condensation and reactions of thiazolidines with chloroformates or halo-acetic acid esters. Furthermore, 5-Arylidene-2,4-thiazolidinediones and their 2-thioxo analogs containing halogen and hydroxy groups or di(benzyloxy) substituents in 5-benzylidene moiety are tested for antifungal activity in vitro. Some of the synthesized compounds exhibit high antifungal activity, both fungistatic and fungicidal, and lead to morphological changes in the yeast cell wall.

Evaluation of New Antimicrobial Agents Based on (1-Indol-3-yl)methylium Salts: Activity, Toxicity, Suppression of Experimental Sepsis in Mice.

The antimicrobial activity and toxicity of three novel synthetic antibacterial agents containing (1-indol-3-yl)methylium fragment were studied in vitro and in vivo. All compounds in vitro revealed high activity (minimal inhibitory concentration (MIC) 0.13-1.

-(Hydroxyalkyl) Derivatives of (1-indol-3-yl)methylium Salts as Promising Antibacterial Agents: Synthesis and Biological Evaluation.

The wide spread of pathogens resistance requires the development of new antimicrobial agents capable of overcoming drug resistance. The main objective of the study is to elucidate the effect of substitutions in (1-indol-3-yl)methylium derivatives on their antibacterial activity and toxicity to human cells. A series of new compounds were synthesized and tested.

Synthesis and antimicrobial activity of 3,4-bis(arylthio)maleimides.

A series of 3,4-bis(arylthio)maleimides were synthesized and their antimicrobial activity was evaluated against Gram-positive and Gram-negative bacteria, including multidrug resistant (MDR) strains and some fungi. Most compounds turned out to be highly active, activity being dependent on substituents on phenyl rings.

Latching chains in K-nearest-neighbor and modular small-world networks.

Latching dynamics retrieve pattern sequences successively by neural adaption and pattern correlation. We have previously proposed a modular latching chain model in Song et al. (2014) to better accommodate the structured transitions in the brain.

Search for inhibitors of bacterial and human protein kinases among derivatives of diazepines[1,4] annelated with maleimide and indole cycles.

Aminomethylation of 9b,10-dihydro-1H-indolo[1,7:4,5,6]pyrrolo[3,4:2,3][1,4]diazepino-[1,7-a]indole-1,3(2H)-diones or 1H-indolo[1,7:4,5,6]pyrrolo[3,4:2,3][1,4]diazepino[1,7-a]indole-1,3(2H)-diones resulted in dialkylaminomethyl derivatives. Alkylation of the nitrogen atom of maleimide moiety of polyannelated diazepines with 1,3-dibromopropane and subsequent reaction with thiourea or its N-alkyl derivatives gave isothiourea-carrying compounds. The compounds containing isothiourea moiety were active against individual human serine/threonine and tyrosine kinases at low micromolar concentrations.
