Synthesis of some 5-(substituted benzylidene)-3-phenyl-2-phenylimino-1,3-thiazolidin-4-ones under ultrasound irradiation

Recently, we have synthesized environmental benign one pot synthesis of 5-(Substituted Benzylidene)-3-Phenyl-2-Phenylimino-1,3-Thiazolidin-4-Ones (a-f) under Ultrasound irradiation by cyclization of 1,3 -diphenylthiourea with a-halo acids in presence of sodium acetate in absolute ethanol for 10-15 minute. The crude compound was purified by silica gel column chromatography using n-hexane and ethyl acetate as solvent system and recrystalised from ethanol. The synthesized compounds have been screened in vitro for their antimicrobial activity against S. aureus and E.coli as compare with standard drug Streptomycin. Some of the compounds displayed pronounced biological activity. The resulting products were characterized by IR,1H NMR and13 C NMR spectroscopic method.

Molecules with versatile biological activities bearing antipyrinyl nucleus as pharmacophore

Antipyrine (1,2-dihydro-1,5-dimethyl-2-phenylpyrazole-3-one) in a structural frame consists of a five membered lactam pyrazolone heterocyclic ring as a pharmacophore moiety. It is evident from literature that the molecules having nitrogen bearing heterocyclic nuclei clearly exhibit several biological actions. Commercially available pyrazolone derivatives as drugs, analgin and metamizol are an established chemical class of analgesics. Recent trends of synthetic routes and several biological actions of antipyrine analogues are considered in this review. Indeed, the synthesized derivatives possess antipyrine moiety having versatile biological properties, antimicrobial, antitubercular, anthelmintic, antioxidant, analgesic, anti-inflammatory, cytotoxic and antiviral activities.

The Rhodadyns, a new class of small molecule inhibitors of dynamin gtpase activity

Six focused rhodanine-based libraries, 60 compounds in total, were synthesized and evaluated as potential dynamin I GTPase inhibitors. Twenty-six were more potent than the lead compound with 13 returning IC50 values ?10 muM, making the Rhodadyn series among the most active dynamin inhibitors reported. Two analogues were highly effective at blocking receptor-mediated endocytosis: C10 and D10 with IC50(RME) = 7.0 ¡À 2.2 and 5.9 ¡À 1.0 muM, respectively. These compounds are equipotent with the best reported in-cell dynamin inhibitors.

New prospects for the development of selective inhibitors of alpha-glucosidase based on coumarin-iminothiazolidinone hybrids: Synthesis, in-vitro biological screening and molecular docking analysis

alpha-Glucosidase inhibitors have extensively been exploited for the effective management of type 2 diabetes and associated complications by significantly reducing the postprandial increase in glucose and plasma insulin levels. In this endeavour, we designed and synthesized a new series of coumarinyl iminothiazolidinone hybrid compounds (6a?o) using a one-pot multi-component approach. The hybrid structures were accessed in good chemical yields. The synthesized compounds were tested for their glucosidase inhibitory efficacy using acarbose as a standard inhibitor (IC50 = 38.2 ¡À 0.12 muM). In-vitro analysis of the hybrid molecules identified several potential leads for the development of potent glucosidase inhibitors with IC50 values in the range of 0.09?0.92 muM with compound 6g being the most potent drug candidate (IC50 = 0.09 ¡À 0.001 muM). Furthermore, compound 6f was identified as the lead inhibitor against maltase-glucoamylase with comparable inhibitory efficacy to acarbose with an IC50 value of 0.07 ¡À 0.016 muM. Binding interactions of potent compounds with the key residues in the active site of the glucosidase enzyme were revealed by molecular docking analysis. In summary, these new structural leads based on the hybrid pharmacophores could be developed as potential inhibitors of alpha-glucosidase for treating postprandial hyperglycemia.

Roles of pyridine and pyrimidine derivatives as privileged scaffolds in anticancer agents

Background: Cancer has been considered to be a global health concern due to the impact of disease on the quality of life. The continual increase of cancer cases as well as the resistance of cancer cells to the existing drugs have driven the search for novel anticancer drugs with better potency and selectivity, improved pharmacokinetic profiles, and minimum toxicities. Pyridine and pyrimidine are presented in natural products and genetic materials. These pyridine/pyrimidine core structures have been noted for their roles in many biological processes as well as in cancer pathogenesis, which make such compounds become attractive scaffolds for discovery of novel drugs. Results & Conclusion: In the recent years, pyridine- and pyrimidine-based anticancer drugs have been developed based on structural modification of these core structures (i.e., substitution with moieties and rings, conjugation with other compounds, and coordination with metal ions). Detailed discussion is provided in this review to highlight the potential of these small molecules as privileged scaffolds with attractive properties and biological activities for the search of novel anticancer agents.

N-Nitroso Sultams: On the Direction of Approach of Nucleophiles to the Sulfonyl Group

The N-nitroso derivatives of propanesultam, butanesultam, and pentanesultam were synthesized along with N-nitropropanesultam and N-nitro-N-methylmethanesulfonamide.The decompositions of the N-nitroso sultams, wich increase in rate with increasing ring size, yield the corresponding sultones and also varying amounts of regenerated sultams.These reactions are discussed in terms of higher energy pathway involving approach of the nucleophile in a direction between of sulfonyl oxygens (on the O, O, N face) and a lower energy pathway involving the conformer which permits approach of the nucleophile trans to and colinear with one of the coordinate covalent oxygen atoms (on R, O, N face). The mechanisms of the decomposition of the N-nitro sulfonamides and the tosyloxy diimide N-oxides are also discussed.N-nitrosopropanesultam (and the butyl analoque) are potent inhibitors of proteinase alpha-chymotrypsin.

Saturated Five-Membered Thiazolidines and Their Derivatives: From Synthesis to Biological Applications

In past decades, interdisciplinary research has been of great interest for scholars. Thiazolidine motifs behave as a bridge between organic synthesis and medicinal chemistry and compel researchers to explore new drug candidates. Thiazolidine motifs are very intriguing heterocyclic five-membered moieties present in diverse natural and bioactive compounds having sulfur at the first position and nitrogen at the third position. The presence of sulfur enhances their pharmacological properties, and, therefore, they are used as vehicles in the synthesis of valuable organic combinations. They show varied biological properties viz. anticancer, anticonvulsant, antimicrobial, anti-inflammatory, neuroprotective, antioxidant activity and so on. This diversity in the biological response makes it a highly prized moiety. Based on literature studies, various synthetic approaches like multicomponent reaction, click reaction, nano-catalysis and green chemistry have been employed to improve their selectivity, purity, product yield and pharmacokinetic activity. In this review article, we have summarized systematic approaches for the synthesis of thiazolidine and its derivatives, along with their pharmacological activity, including advantages of green synthesis, atom economy, cleaner reaction profile and catalyst recovery which will help scientists to probe and stimulate the study of these scaffolds.

Synthetic 2-aryl-3-((piperidin-1-yl)ethyl)thiazolidin-4-ones exhibit selective in?vitro antitumoral activity and inhibit cancer cell growth in a preclinical model of glioblastoma multiforme

Glioblastoma multiforme (GBM) is the worst form of primary brain tumor, which has a high rate of infiltration and resistance to radiation and chemotherapy, resulting in poor prognosis for patients. Recent studies show that thiazolidinones have a wide range of pharmacological properties including antimicrobial, anti-inflammatory, anti-oxidant and anti-tumor. Here, we investigate the effect antiglioma in?vitro of a panel of sixteen synthetic 2-aryl-3-((piperidin-1-yl)ethyl)thiazolidin-4-ones where 13 of these decreased the viability of glioma cells 30?65% (100?muM) compared with controls. The most promising compounds such as 4d, 4l, 4m and 4p promoted glioma reduction of viability greater than 50%, were further tested at lower concentrations (12.5, 25, 50 and 100?muM). Also, the data showed that the compounds 4d, 4l, 4m and 4p induced cell death primarily through necrosis and late apoptosis mechanisms. Interestingly, none of these 2-aryl-3-((piperidin-1-yl)ethyl)thiazolidin-4-ones were cytotoxic for primary astrocytes, which were used as a non-transformed cell model, indicating selectivity. Our results also show that the treatment with sub-therapeutic doses of 2-aryl-3-((piperidin-1-yl)ethyl)thiazolidin-4-ones (4d, 4l and 4p) reduced in?vivo glioma growth as well as malignant characteristics of implanted tumors such as intratumoral hemorrhage and peripheral pseudopalisading. Importantly, 2-aryl-3-((piperidin-1-yl)ethyl)thiazolidin-4-ones treatment did not induce mortality or peripheral damage to animals. Finally, 2-aryl-3-((piperidin-1-yl)ethyl)thiazolidin-4-ones also changed the nitric oxide metabolism which may be associated with reduced growth and malignity characteristics of gliomas. These data indicates for the first time the therapeutic potential of synthetic 2-aryl-3-((piperidin-1-yl)ethyl)thiazolidin-4-ones to GBM treatment.
