Design, synthesis, and biological evaluation of N,N-disubstituted-4-arylthiazole-2-methylamine derivatives as cholesteryl ester transfer inhibitors

Cholesteryl ester transfer protein (CETP) has been identified as a potential target for cardiovascular disease (CVD) for its important role in the reverse cholesteryl transfer (RCT) process. In our previous work, compound 5 was discovered as a moderate CETP inhibitor. The replacement of the amide linker by heterocyclic aromatics and then a series of N,N-substituted-4-arylthiazole-2-methylamine derivatives were designed by utilizing a conformational restriction strategy. Thirty-six compounds were synthesized and evaluated for their CETP inhibitory activities. Structure-activity relationship studies indicate that electron donor groups substituted ring A, and electron-withdrawing groups at the 4-position of ring B were critical for potency. Among these compounds, compound 30 exhibited excellent CETP inhibitory activity (IC50 = 0.79 ¡À 0.02 muM) in vitro and showed an acceptable metabolic stability.

Synthesis and Antiallergic Activity of Some Acidic Derivatives of 4H-Pyrimido<2,1-b>benzazol-4-ones

Reactions of 2-aminobenzothiazole, 2-aminobenzoxazole, and 2-amino-1-methylbenzimidazole with dimethyl aminofumarate (DMAF) or diethyl ethoxymethylenemalonate (DEEM) led to 2- or 3-carboxy-4H-pyrimido<2,1-b>benzazol-4-ones, respectively.Subsequent derivatization of these carboxylic acids gave the corresponding tetrazolylcarboxamides and tetrazoles.These acidic compounds were tested in the rat passive cutaneous anaphylaxis (PCA) assay as potential antiallergic agents.Many of the compounds displayed activity comparable to that shown by disodium cromoglycate (DSCG) when tested by the intraperitoneal route, and some, unlike DSCG, also showed activity when tested orally.

Effects of ammonium phosphate on the formation of crystal copper sulfide on chrysocolla surfaces and its response to flotation

In this study, for the first time, we applied ammonium phosphate to pre-treat chrysocolla prior to sulfidization flotation. In addition, we investigated the structural characteristics of the copper sulfide film formed on the chrysocolla surfaces and its response to flotation. Micro-flotation experiments revealed that the addition of (NH4)3PO4 prior to sulfidization greatly improves the floatability of chrysocolla and its recovery increased from 8.71% to 87.97% with butyl xanthate as the collector. The results of the field emission scanning electron microscopy analysis showed that numerous regular fragments appeared on the chrysocolla surfaces after the addition of (NH4)3PO4. The X-ray diffraction and X-ray photoelectron spectrometry analysis confirmed that these fragments were newly formed copper sulfide covering the chrysocolla surfaces, during this process a chemical reaction occurred in the slurry system, i.e. the Cu2+ were reduced to Cu+, the S2? were mainly oxidized to S?, (S2)?, (S2)2?. The copper sulfide species primarily in the form of crystalline covellite (Cu+ 3(S2)2?S?), which is the key to obtaining good flotation recovery. As a specific activator, (NH4)3PO4 participates in the liquid-solid phase chemical reaction between the sulfidizing reagent and the chrysocolla, which promotes the sulfidization reaction of chrysocolla.

Effects of catalpol on the activity of human liver cytochrome P450 enzymes

1. Catalpol possesses numerous pharmacological activities, and however, little data available for the effects of catalpol on the activity of human liver cytochrome P450 (CYP) enzymes. 2. This study investigates the inhibitory effects of catalpol on the main human liver CYP isoforms. In this study, the inhibitory effects of catalpol on the eight human liver CYP isoforms 1A2, 2A6, 2E1, 2D6, 2C9, 2C19, 2C8 and 3A4 were investigated in human liver microsomes. 3. The results indicated that catalpol could inhibit the activity of CYP3A4, CYP2E1 and CYP2C9, with IC50 values of 14.27, 22.4 and 14.69 muM, respectively, but those other CYP isoforms were not affected. Enzyme kinetic studies showed that catalpol was not only a noncompetitive inhibitor of CYP3A4, but also a competitive inhibitor of CYP2E1 and CYP2C9, with Ki values of 7.40, 10.75 and 7.37 muM, respectively. In addition, catalpol is a time-dependent inhibitor for CYP3A4, with maximum inactivation (kinact) and 50% maximum inactivation (KI) values of 0.02 min?1 and 1.86 muM, respectively. 4. The in vitro studies of catalpol with CYP isoforms suggest that catalpol has the potential to cause pharmacokinetic drug interactions with other co-administered drugs metabolized by CYP3A4, CYP2E1 and CYP2C9. Further in vivo studies are needed in order to evaluate the significance of this interaction.

An update on the synthesis of benzoxazoles

Benzoxazoles being structurally similar to bases adenine and guanine interact with biomolecules present in living systems. These compounds possess antimicrobial, central nervous system activities, antihyperglycemic potentiating activity, analgesic, and anti-inflammatory activity. It can also be used as starting material for other bioactive molecules. Modifications in structure and the biological profiles of new generations of benzoxazoles were found to be more potent with enhanced biological activity. Considering all these, we have prepared this review and discussed the synthesis and biological activities of benzoxazoles.

Antineoplastic agents. 556. Isolation and structure of coprinastatin 1 from coprinus cinereus

Cancer cell line bioassay-guided separation of an ethyl acetate extract prepared from a plant-associated fungus, Coprinus cinereus, led to the isolation of three new sesquiterpenes, coprinastatin 1 (1), coprinol (2), and the epimer (4a), of the known sesquiterpene triol 4b. The previously described sesquiterpene 3 and oxazolinone 5 were also isolated. The structure and relative configuration of coprinastatin 1 (1) were determined by HRMS and by ID- and 2D-NMR spectroscopic analyses. The structure of terpene 2 was elucidated by single-crystal X-ray diffraction experiments. The remaining structures were similarly determined, structure 3 by spectroscopic analyses and both 4a and 5 by X-ray crystal structure determination. Coprinastatin 1 (1.) was found to inhibit growth of the murine P388 lymphocytic leukemia cell line and the pathogenic bacterium Neisseria gonorrhoeae.

1,2,4-Triazole-based benzothiazole/benzoxazole derivatives: Design, synthesis, p38alpha MAP kinase inhibition, anti-inflammatory activity and molecular docking studies

Novel N-(benzothiazol/oxazol-2-yl)-2-[(5-(phenoxymethyl)-4-aryl-4H-1,2,4-triazol-3-yl)thio] acetamide derivatives (5a-n) were synthesized and investigated for in vitro anti-inflammatory activity and p38alpha MAP kinase inhibition. Compounds showing good in vitro activities (5a, 5b, 5d, 5e, 5i, 5k and 5l) were studied for their in vivo anti-inflammatory activity using carrageenan induced rat paw edema model. Compound 5b emerged as the most active compound with an edema inhibition of 84.43%. It also showed improved GI safety profile with lower ulcer severity index and lipid peroxidation potential. Also, p38alpha MAP kinase assay of 5b showed superior inhibitory potency (IC50:0.031 ¡À 0.14 muM) than the standard SB 203580 (IC50:0.043 ¡À 0.14 muM). To predict their binding mode compounds were also docked against p38alpha MAP kinase enzyme. Compound 5b and SB 203580 showed hinge region interaction with MET 109.
