Effects of a heterogeneous set of xenobiotics on RNA synthesis of yeast cells

Previously the toxicity of 45 heterogeneous environmental chemicals on growth and membrane functions in Saccharomyces cerevisiae and Chinese hamster ovary (CHO) cells (Cascorbi et al., 1993) was examined. In this study the inhibitory effects of the same set of chemicals on yeast RNA synthesis rate, measuring [2-14C]uracil uptake during cell proliferation are presented. The sensitivity of this test system was three to six times higher than that of the proliferation rate assay. In addition, the range of the EC20 values were similar to the range from the mammalian CHO cell proliferation test. The relatively good correlation with the yeast cell growth rate (r = 0.78, P = 0.0001) suggests that yeast RNA synthesis is a simple and rapid method of detecting a wide range of toxic compounds without the disadvantage of the insensitivity of the growth rate assay.

Design, synthesis and anti-tuberculosis activity of 1-adamantyl-3- heteroaryl ureas with improved in vitro pharmacokinetic properties

Out of the prominent global ailments, tuberculosis (TB) is still one of the leading causes of death worldwide due to infectious disease. Development of new drugs that shorten the current tuberculosis treatment time and have activity against drug resistant strains is of utmost importance. Towards these goals we have focused our efforts on developing novel anti-TB compounds with the general structure of 1-adamantyl-3-phenyl urea. This series is active against Mycobacteria and previous lead compounds were found to inhibit the membrane transporter MmpL3, the protein responsible for mycolic acid transport across the plasma membrane. However, these compounds suffered from poor in vitro pharmacokinetic (PK) profiles and they have a similar structure/SAR to inhibitors of human soluble epoxide hydrolase (sEH) enzymes. Therefore, in this study the further optimization of this compound class was driven by three factors: (1) to increase selectivity for anti-TB activity over human sEH activity, (2) to optimize PK profiles including solubility and (3) to maintain target inhibition. A new series of 1-adamantyl-3-heteroaryl ureas was designed and synthesized replacing the phenyl substituent of the original series with pyridines, pyrimidines, triazines, oxazoles, isoxazoles, oxadiazoles and pyrazoles. This study produced lead isoxazole, oxadiazole and pyrazole substituted adamantyl ureas with improved in vitro PK profiles, increased selectivity and good anti-TB potencies with sub mug/mL minimum inhibitory concentrations.

Design and synthesis of NO-releasing betulinic acid derivatives as potential anticancer agents

A total of 16 targeted NO-releasing betulinic acid (BA) derivatives were designed and synthesized as potential anticancer agents. Most IC50 values were under 1.0 muM in vitro test against HepG2 and B16. The result suggested that derivatives of BA with alpha,beta-unsaturated ketone skeleton possessed significant cytotoxic activities than the others, among which derivatives with three carbons in diol linker (15b and 15c) exhibited the highest anti-cancer activity. NO-releasing amount detection of partial target compounds suggested that NO-releasing amount of this series of BA derivatives positively correlates with their cytotoxic activities. The anti-angiogenic activity of partial target compounds on zebrafish embryos in our experiment did not show any effects on the SIVs, however, they exhibited different influence on ISVs, with only 15a and 15d better than the negative control.

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 288-14-2, help many people in the next few years.Computed Properties of C3H3NO

Synthesis and evaluation of anticonvulsant activities of 5-benzylidene-2-(5-methylisoxazol-3-ylimino)thiazolidin-4-one derivatives

Fifteen new 5-benzylidene-2-(5-methylisoxazol-3-ylimino)thiazolidin-4-one derivatives (4-18) were synthesized and evaluated for their preliminary anticonvulsant activity and neurotoxicity by using the maximal electroshock (MES) and rotarod tests. The structures of synthesized compounds were established by IR,1H NMR,13C NMR and mass spectral data. Among the compounds studied, 5-(3-fluorobenzylidene)-2-(5-methylisoxazol-3-ylimino)thiazolidin-4-one (8) was the most potent compound, with a median effective dose of 43.9 mg/kg and a high protective index (PI) of more than 11.1 after intraperitoneal administration in mice. Compound 8 showed significant oral activity against MES-induced seizures in mice, with an ED50 of 84.2 mg/kg and a PI above 11.8. These results demonstrate that compound 8 is safer than the commercially drugs.

Evolution of PIKK family kinase inhibitors: A new age cancer therapeutics

Phosphatidylinositol-3 kinase-related kinases (PIKKs) belong to a family of atypical serine/threonine kinases in humans. They actively participate in a diverse set of cellular functions such as meiotic, V(D)J recombination, chromosome maintenance, DNA damage sensing and repair, cell cycle progression and arrest. ATR, ATM, DNA-PKcs, mTOR and hSMG are the members of the PIKK family that play an important role in in cancer cell proliferation, autophagy, and cell survival to radio and chemotherapy. Thereby targeting these PIKK kinases in cancer along with chemo/radiotherapy agents, can help in differential cytotoxicity towards cancer cell over the normal cell. In this review, we compile the various small molecule kinase inhibitors with respect to structural and strategic targeting of PIKK family members. Rapalogs, AZD8055, AZD2014, OSI-027, INK-128, MLN0128, VX970, NVP-BEZ235, Torin2, AZ20, and AZ31 are the diverse scaffolds which have successfully made into the pre-clinical trials either as mono or combinatorial therapy for the treatment of various human cancers. Their synthesis and pre-clinical trial highlight the challenges associated in the development process.

Design, synthesis and evaluation of novel polypharmacological antichlamydial agents

Abstract Discovery of new polypharmacological antibacterial agents with multiple modes of actions can be an alternative to combination therapy and also a possibility to slow development of antibiotic resistance. In support to this hypothesis, we synthesized 16 compounds by combining the pharmacophores of Chlamydia trachomatis inhibitors and inhibitors of type III secretion (T3S) in gram-negative bacteria. In this study we have developed salicylidene acylhydrazide sulfonamides (11c & 11d) as new antichlamydial agents that also inhibit T3S in Yersinia pseudotuberculosis.
