Discovery of 1,3-diphenyl-1H-pyrazole derivatives containing rhodanine-3-alkanoic acid groups as potential PTP1B inhibitors

Two series of 1,3-diphenyl-1H-pyrazole derivatives containing rhodanine-3-alkanoic acid groups were identified as competitive protein tyrosine phosphatase 1B (PTP1B) inhibitors. Among the compounds studied, IIIv was found to have the best in vitro inhibition activity against PTP1B (IC50 = 0.67 ¡À 0.09 muM) and the best selectivity (9-fold) between PTP1B and T-cell protein tyrosine phosphatase (TCPTP). Molecular docking studies demonstrated that compounds IIIm, IIIv and IVg could occupy simultaneously at both the catalytic site and the adjacent pTyr binding site. These results provide novel lead compounds for the design of inhibitors of PTP1B as well as other PTPs.

Novel rhodanine derivatives induce growth inhibition followed by apoptosis

We have designed and synthesized three novel compounds, 5-isopropylidiene derivatives of 3-dimethyl-2-thio-hydantoin (ITH-1), 3-ethyl-2-thio-2,4- oxazolidinedione (ITO-1), and 5-benzilidene-3-ethyl rhodanine (BTR-1), and have tested their chemotherapeutic properties. Our results showed that all three compounds induced cytotoxicity in a time- and concentration-dependent manner on leukemic cell line, CEM. Among the compounds tested, BTR-1 was 5- to 7-fold more potent than ITH-1 and ITO-1 when compared by trypan blue and MTT assays. IC50 value of BTR-1 was estimated to be <10 muM. Both cell cycle analysis and tritiated thymidine assays revealed that BTR-1 affects DNA replication by inducing a block at S phase. BTR-1 treatment led to increased level of ROS production and DNA strand breaks suggesting activation of apoptosis for induction of cell death. 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 18331-34-5, help many people in the next few years.Quality Control of 5-Benzylidene-3-ethyl-2-thioxothiazolidin-4-one

Structure-guided design of thiazolidine derivatives as mycobacterium tuberculosis pantothenate synthetase inhibitors

The pantothenate biosynthetic pathway is essential for the persistent growth and virulence of Mycobacterium tuberculosis (Mtb) and one of the enzymes in the pathway, pantothenate synthetase (PS, EC: 6.3.2.1), encoded by the panC gene, has become an appropriate target for new therapeutics to treat tuberculosis. Herein, we report nanomolar thiazolidine inhibitors of Mtb PS developed by a rational inhibitor design approach. The thiazolidine compounds were discovered by using energy-based pharmacophore modelling and subsequent in vitro screening, which resulted in compounds with a half maximal inhibitory concentration (IC50) value of (1.12¡À0.12) muM. These compounds were subsequently optimised by a combination of modelling and synthetic chemistry. Hit expansion of the lead by chemical synthesis led to an improved inhibitor with an IC50 value of 350 nM and an Mtb minimum inhibitory concentration (MIC) of 1.55 muM. Some of these compounds also showed good activity against dormant Mtb cells.

Design, synthesis and biological evaluation of 4-anilinoquinoline derivatives as novel potent tubulin depolymerization agents

A series of novel 4-anilinoquinoline derivatives were synthesized and evaluated for their antiproliferative activities. Among them, 14h exhibited the most potent cytotoxic activity with IC50 values ranging from 1.5 to 3.9 nM against all tested cancer cell lines, and showed promising efficacy in multidrug resistant cancer cells. Flow cytometry assay, immune-fluorescence staining, microtubule dynamics assays and competition assays with EBI identified that 14h was a novel tubulin depolymerization agent by binding to the colchicine site. Importantly, in vivo efficacy evaluation of HCT116 xenograft model, 14h showed efficient antitumor activity without significant loss in body weight. All the results indicated that 14h could be a promising candidate for the treatment of cancer.

PTP1b inhibition, a promising approach for the treatment of diabetes type II

Background: Diabetes Mellitus (DM), is a metabolic disorder characterized by high blood glucose levels. The main types of diabetes mellitus are Diabetes mellitus type I, Diabetes mellitus type II, gestational diabetes and Diabetes of other etiology. Diabetes type II, the Non Insulin Dependent Type (NIDDM) is the most common type, characterized by the impairment in activation of the intracellular mechanism leading to the insertion and usage of glucose after interaction of insulin with its receptor, known as insulin resistance. Although, a number of drugs have been developed for the treatment of diabetes type II, their ability to reduce blood glucose levels is limited, while several side effects are also observed. Furthermore, none of the market drugs targets the enhancement of the action of the intracellular part of insulin receptor or recuperation of the glucose transport mechanism in GLUT4 dependent cells. The Protein Tyrosine Phosphatase (PTP1b) is the main enzyme involved in insulin receptor desensitization and has become a drug target for the treatment of Diabetes type II. Several PTP1b inhibitors have already been found, interacting with the binding site of the enzyme, surrounding the catalytic amino acid Cys215 and the neighboring area or with the allosteric site of the enzyme, placed at a distance of 20 A from the active site, around Phe280. However, the research continues for finding more potent inhibitors with increased cell permeability and specificity. Objective: The aim of this review is to show the attempts made in developing of Protein Tyrosine Phosphatase (PTP1b) inhibitors with high potency, selectivity and bioavailability and to sum up the indications for favorable structural characteristics of effective PTP1b inhibitors. Methods: The methods used include a literature survey and the use of Protein Structure Databanks such as PuBMed Structure and RCSB and the tools they provide. Conclusion: The research for finding PTP1b inhibitors started with the design of molecules mimicking the Tyrosine substrate of the enzyme. The study revealed that an aromatic ring connected to a polar group, which preferably enables hydrogen bond formation, is the minimum requirement for small inhibitors binding to the active site surrounding Cys215. Molecules bearing two hydrogen bond donor/acceptor (Hb d/a) groups at a distance of 8.5-11.5 A may form more stable complexes, interacting simultaneously with a secondary area A2. Longer molecules with two Hb d/a groups at a distance of 17 A or 19 A may enable additional interactions with secondary sites (B and C) that confer stability as well as specificity. An aromatic ring linked to polar or Hb d/a moieties is also required for allosteric inhibitors. A lower distance between Hb d/a moieties, around 7.5 A may favor allosteric interaction. Permanent inhibition of the enzyme by oxidation of the catalytic Cys215 has also been referred. Moreover, covalent modification of Cys121, placed near but not inside the catalytic pocket has been associated with permanent inhibition of the enzyme.
