Cancer is the second leading cause of death worldwide. There is always a huge demand for novel anticancer drugs and diverse new natural or synthetic compounds are developed continuously by scientists. Presently, a large number of drugs in clinical practice have showed pervasive side effect and multidrug resistance. Sulfonyl or sulfonamide hybrids became one of the most attractive subjects due to their broad spectrum of pharmacological activities. Sulfonyl hybrids were broadly explored for their anticancer activities and it was found that they possess minimum side effect along with multi-drug resistance activity. This review describes the most recent applications of sulfonyl hybrid analogues in anticancer drug discovery and further discusses the mechanistic insights, structure-activity relationships and molecular docking studies for the potent derivatives.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2682-49-7, help many people in the next few years.Formula: C3H5NOS

The structurally simple (Me3P)2NiCl2 complex catalyzes SN1-type alkylations of chiral N-acyl thiazolidinethiones with diarylmethyl methyl ethers and other stable carbenium cations. The former can contain a variety of functional groups and heteroatoms at the alpha-position. The resultant adducts are isolated as single diastereomers in high yields and can be converted into enantiomerically pure derivatives in a straightforward manner.

Application of 76186-04-4, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst.

Enantioselective approaches to the construction of four complex building blocks of the structurally intricate marine macrolide known as spongistatin 1 are presented. The first phase of the synthetic effort relies on a practical approach to a desymmetrized, enantiomerically pure spiroketal ring system incorporating rings A and B. Concurrently, the C17-C28 subunit, which houses one-fifth of the stereogenic centers of the target in the form of rings C and D, was assembled via a composite of stereocontrolled aldol condensations. Once arrival at the entire C1-C28 sector had been realized, routes were devised to provide two additional highly functionalized sectors consisting of C29-C44 and C38-C51. A series of subsequent transformations including cyclization of the E ring and hydroboration to afford the B-alkyl intermediate for the key Suzuki coupling to append the side chain took advantage of efficient stereocontrol. Ultimately, complete assembly and functionalization of the western EF sector of spongistatin was thwarted by an inoperative Suzuki coupling step intended to join the side chain to the C29-C44 sector, and later because of complications due to protecting groups, which precluded the complete elaboration of the late stage C29-C51 intermediate.

Aim. Synthesis of a series of thiazolidinone-and pyrazoline-related compounds. In vitro screening of antiplasmodial activity of versatile heterocyclic derivatives. Methods: Organic wet synthesis, analytical and spectral methods, pharmacological screening, SAR analysis. Results. A series of different thiazolidinone-and pyrazoline-based derivatives was screened against Plasmodium falciparum in in vitro assays. 5-(Z)-Arylidene-2-arylidenehydrazono-3-(4-hydroxyphenyl)-4-thiazolidinones showed high growth inhibition rates with the IC50-2.32-2.39 muM. 5-Bromo-1-[2-[3-(4-chlorophenyl)-5-(4-methoxyphenyl)-3,4-dihydropyrazol-2-yl]-2-oxoethyl]indoline-2,3-dione 3 was the most active compound among tested with the IC50-1.81 muM. Based on the screening data some structure-activity relationships were derived. Conclusions. A set of different thiazolidinone-and pyrazoline-related derivatives with antitrypanosomal and anticancer properties was screened against Plasmodium falciparum. Hitcompounds inhibiting growth of the parasite at micromolar concentrations were identified. The obtained results provide further avenues to develop more potent antimalarial agents on the base of investigated classes of small drug-like molecules.

Leishmaniasis is a neglected tropical disease caused by around 20 species of obligate intramacrophage protozoa of the genus Leishmania. This disease is an important cause of morbidity and mortality that primarily impacts the poorest populations living in tropical and sub-tropical regions of the world, but has become of concern in some developed countries. The resistance of leishmanial parasites to the drugs available and their undesirable side effects have prompted the discovery of new synthetic compounds with potent antileishmanial activity and fewer side effects that can serve as new therapeutic agents. In this article, we make a comprehensive review of the most recent advances of synthetic compounds with antileishmanial activity (from 2015 to the early 2017). Furthermore, we covered the structure- activity relationship studies that allow for optimization and selection of the most promising drugs, and the biochemical mechanisms that explain the antileishmanial activities observed.

Neglected Tropical Diseases (NTDs) affect more than a billion people worldwide, mainly populations living in poverty conditions. More than 56% of annual NTD deaths are caused by Leishmaniasis, Sleeping sickness, and Chagas disease. For these three diseases, many problems have been observed with the chemotherapeutic drugs commonly used, these being mainly resistance, high toxicity, and low efficacy. In the search for alternative treatments, hybridization is an interesting approach, which generates new molecules by merging two pharmacophores and then looking for improvements in biological activity or reduced compound toxicity. Here, we review various studies that present such hybrid molecules with promising in vitro and in vivo activities against Leishmania and Trypanosoma parasites.

Background: Diseases caused by microbial infections are very common worldwide. Although the search of innovative antimicrobial agents is the current focus for the researchers, the treatment of infectious diseases remains an important public health issue and a challenging problem in front of medicinal chemist. Methods: A series of 2-(4-hydroxyphenyl)-3-(4-(4-nitrophenyl) thiazol-2-yl)thiazolidin-4-one derivatives (T1-T10) was designed and synthesized. All the titled compounds were evaluated for their antimicrobial potential. Antimicrobial activity was performed by tube dilution methods against Gram negative Escherichia coli MTCC 443 (E. Coli), Gram positive bacteria: Staphylococcus aureus MTCC 3160 (S. aureus) and Bacillus subtilis MTCC 441 (B. Subtilis), and fungal strains: Aspergillus niger MTCC 281 (A. niger) and Candida albicans MTCC 227 (C. albicans). Results: Among the synthesized derivatives, compounds 2, 4 and 10 were found to be most active antimicrobial agents. Conclusion: In conclusion, a series of 2-(phenyl)-3-(4-(phenyl)thiazol-2-yl)thiazolidin-4-ones have been designed and synthesized. All the titled compounds were evaluated for their in vitro antimicrobial activity against five representative microorganisms. The results of antimicrobial study indicated that the presence of nitro and chloro groups in aromatic ring improved antibacterial activity, whereas the presence of hydroxy group improved antifungal activity of substituted 4-thiazolidinone derivatives.
