Objective: Isatins have emerged as antimicrobial agents due to their broad spectrum of in vitro and in vivo antimicrobial activities. In addition, thiazolidinone also reported to possess various biological activities particularly antimicrobial activity. Due to the importance, we planned to synthesize compounds with isatin functionality coupled with thiazolidinone as possible antitubercular and antimicrobial agents which could furnish better therapeutic results. Methods: In vitro Mycobacterium tuberculosis method and agar streak dilution test are used to estimate antitubercular and antimicrobial potency of title analogs, respectively. Minimum inhibitory concentration of entire title compounds was determined against all tested microorganism such as M. tuberculosis, four Gram-positive, three Gram-negative bacteria, and two fungi. Results: A series of new thiazolidinone substituted Schiff and Mannich bases of 5-nitroisatins were designed and synthesized by a multistep synthesis from isatin. Structures of synthesized compounds are characterized using Fourier-transform infrared, proton nuclear magnetic resonance, mass spectroscopy, and bases of elemental analysis. Mild to good antitubercular and antimicrobial activity was showed by synthesized 5-nitroisatin analogs. The relationship between the biological activity and the functional group variation of the tested compounds was discussed. Conclusion: 3-(4-(3-(4-Aminophenyl)-4-oxothiazolidin-2-yl)phenylimino)-1-((dimethyl amino)methyl)-5-nitroindolin-2-one 6 and 3-(4-(3-(2-aminophenyl)-4-oxothiazolidin-2-yl)phenylimino)-1-((dimethylamino)methyl)-5-nitroindolin-2-one 13 were found to be the most potent compounds of this series which might be extended as a novel class of antimicrobial agents.

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.

The polyunsaturated lipid mediator PD1n-3 DPA (5) was recently isolated from self-resolving inflammatory exudates of 5 and human macrophages. Herein, the first total synthesis of PD1n-3 DPA (5) is reported in 10 steps and 9% overall yield. These efforts, together with NMR data of its methyl ester 6, confirmed the structure of 5 to be (7Z,10R,11E,13E,15Z,17S,19Z)-10,17- dihydroxydocosa-7,11,13,15,19-pentaenoic acid. The proposed biosynthetic pathway, with the involvement of an epoxide intermediate, was supported by results from trapping experiments. In addition, LC-MS/MS data of the free acid 5, obtained from hydrolysis of the synthetic methyl ester 6, matched data for the endogenously produced biological material. The natural product PD1 n-3 DPA (5) demonstrated potent anti-inflammatory properties together with pro-resolving actions stimulating human macrophage phagocytosis and efferocytosis. These results contribute new knowledge on the n-3 DPA structure-function of the growing numbers of specialized pro-resolving lipid mediators and pathways.

The antioxidants are proving crucial tools in the exploration of oxidant stress-related diabetic pathologies and despite the noticeable prospective merit of the safety and efficacy of antioxidant supplementation in any future treatment remains to be conventional. The development of innovative methods for the synthesis of five-member heterocyclic compounds is an ever-expanding area in bioorganic and medicinal chemistry. Specifically, those containing the thiazolidinedione ring have been expansively used as key building blocks for synthesizing various drugs. In present study we endeavor to display a more chemically versatile and diverse thiazolidin-4-one derivatives as a suitable pharmacophore for antioxidant activity. Antioxidant activity was evaluated by using both enzymatic and non-enzymatic activities such as catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPX) on cell lines and free radical scavenging activity by DPPH (1, 1-diphenyl-2-picryl-hydrazil) assay method and ferric reducing antioxidant power (FRAP) assays. Finally, all tested compounds exhibited a talented antioxidant activity. In addition, all the synthesized derivatives showed non-toxic effects against a diseased human lung fibroblast (COPD), HCC7231 (TACC CCL-96). In prospect study, the movement of the compounds may be manipulated by optimizing a lead molecule by introducing un-saturation or heterocyclic ring at C5 of thiazolidinediones. The outcomes of such studies may be positive for the clinical applications in humans and may open up a new therapeutic avenue.
