Synthesis and evaluation of thiazolidinone-pyrazole conjugates as anticancer and antimicrobial agents

Aim: To synthesize a series of new thiazolidinone-pyrazole hybrids (5a-o) and assess their anticancer (in vitro and in vivo) and antimicrobial activities. Results: The compounds 5h (against Ehrlich ascites carcinoma cells), 5e and 5i (against the human breast cancer [MDA-MB231] cell line) exhibited potent anticancer activity. All the compounds except 5g and 5e found to be less toxic for the human dermal fibroblast cells. The effective interactions of the compounds in silico with MDM2 exemplified their inhibitory potency. The derivatives also showed moderate antimicrobial activity. Conclusion: The halogen atoms on various positions of the N-arylamino ring played an advantageous role in elevating the potency of the molecules. Thus, these conjugates could be used as a lead for further optimization to achieve promising therapeutics.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 2682-49-7, you can also check out more blogs about2682-49-7

Role of salmonella Typhi Vi antigen and secretory systems on immune response

Virulence capsular polysaccharide (Vi antigen) and Salmonella`s Pathogenicity Island type 1 and 2 TTSS (SPI-1 and SPI-2 TTSS) are important membrane virulence factors of human restricted pathogen S. Typhi. The Vi antigen modulates different proinflammatory signaling pathways in infected macrophages, microfold epithelial and dendritic cells. SPI-2 TTSS and its effectors are required for promoting bacterial intracellular survival, replication and apoptosis while SPI-1 and its effectors are associated with invasion of microfold epithelial cells. The purified Vi-antigen has been used as a vaccine against disease. It is a T cell independent antigen that induces moderate efficacy (? 55%) in adults and no efficacy in children bellow two years of age. Carrier protein conjugation of the Vi antigen has been successfully used to confer T cell dependency and to develop Vi conjugate vaccines with high efficacy, around 89% in three years, in all age groups. So far, the attenuated live vaccine with constitutive expression of Vi antigen and the SPI-2 TTSS mutant vaccine, progressed to phase 3 clinical tests. Particularly, the live attenuated vaccine with constitutive expression of Vi antigen might be also used to optimize the efficacies of other vaccines. The current preclinical studies consider also development of novel T cell independent vaccines from recombinant proteins and generalized modules for membrane antigens. An approach for future antivirulence therapy against disease might also consider the bioactive compounds with ability to inhibit TTSS secretions. It is concluded that combined approaches my successfully reduce S. Typhi infection in this new globalized era.

A convenient synthetic method has been developed for accessing 2,6-dialkynyl-3,5-dichloropyridine derivatives in acceptable to good yields. The methodology involved ultrasound assisted site-selective alkynylation of 2,3,5,6-tetrachloropyridines under Pd/C[sbnd]Cu catalysis. A variety of terminal alkynes were employed in this C[sbnd]C coupling reaction to afford the corresponding 2,6-dialkynyl-3,5-dichloropyridine derivatives.

Thiazolidin-4-one derivatives on human lung fibroblast shows oxygen free radical scavenging activity

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.

Comparative docking studies: A drug design tool for some pyrazine-thiazolidinone based derivatives for anti-HIV activity

Background: Acquired immunodeficiency Syndrome (AIDS) is caused by Human immunodeficiency virus type 1 (HIV-1). Pyrazine and Thiazolidinone pharmacophore has diverse biological activities including anti HIV activity. Aims and Objectives: To study binding behavior of Pyrazine-thiazolidinone derivatives on four different crystal structures of HIV-1RT.These molecules which were already reported as anti-TB were investigated for dual activity as Anti-HIV and Anti-TB. Materials and Methods: In the present study we describe a comparative docking study of twenty-three derivatives of N-(4-oxo-2 substituted thiazolidin-3-yl) pyrazine-2-carbohydrazide. Binding pattern of these derivatives was gauged by molecular docking studies on four different receptors bearing PDB code 1ZD1, 1RT2, 1FKP and 1FK9 of HIV?RT enzyme using V. Life MDS software Genetic algorithm docking method. Result and Discussion: The studies revealed hydrogen bonds, hydrophobic interaction and pi-pi interactions playing significant role in binding of the molecules to the enzyme. Conclusion: Most of the molecules have shown good dock score and binding energy with anti-HIV receptors but Molecules 13 and 14 have potential to act as anti-tubercular and Anti HIV and hence can be further explored for dual activity.
