The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.16112-21-3, Name is 2-(4-Methylphenyl)benzothiazole, molecular formula is C14H11NS. In a Article£¬once mentioned of 16112-21-3, SDS of cas: 16112-21-3

Abstract: A simple, convenient, and highly efficient multicomponent one-pot synthesis of highly functionalized piperidines has been developed via tandem reactions of beta-keto esters, aromatic aldehydes, and various amines in ethanol at room temperature using catalytic amount (10?mol%) of a chromium(III)-salen complex nanoparticles supported on AlPO4. The heterogeneous catalyst exhibited excellent activity and reusability (up to 8 times) in the synthesis of highly functionalized piperidines. Also, synthesis of 2-arylbenzimidazoles and 2-arylbenzothiazoles have been efficiently developed under mild condition from o-phenylenediamines or 2-aminothiophenol with aryl aldehydes via one-step process using catalytic amount (2.0?mol%) of nanocatalyst in air atmosphere as a green oxidant. The heterogeneous catalyst was characterized by scanning electron microscopy, atomic force microscopy, inductively coupled plasma spectrometry, thermogravimetry for analysis of nitrogen adsorption, and FT-IR spectroscopy.

For the purpose of obtaining orally potent VLA-4 inhibitors, we have carried out structural modification of the (N?-phenylureido)phenyl group in compound 1, where the group was found to be attributed to poor pharmacokinetic profile in our previous research. Through modification, we have identified several compounds with both potent in vitro activity and improved oral exposure. In particular, compound 7e with 7-fluoro-2-(1-methyl-1H-indol-3- yl)-1,3-benzoxazolyl group as a novel replacement of the (N?-phenylureido) phenyl group significantly inhibited eosinophil infiltration into bronchoalveolar lavage fluid at 15 mg/kg in an Ascaris-antigen-induced murine bronchial inflammatory model, and its efficacy was comparable to that of the anti-mouse alpha4 antibody (R1-2).

A novel two-step synthesis of substituted 2-formylpyrroles Is described. Aldol adducts of ketones and 4-formyloxazole undergo a dehydration/ oxazote hydrolysis/cyclization cascade on sequential treatment with MsCl/Et3N and aqueous NaOH to yield 5-substttuted and 4,5-disubstituted 2-formylpyrroles. The methodology was extended to an N-benzyl thiazolium salt.

In this work we report our results concerning the study on the in vitro antiproliferative activity of 18 Baylis-Hillman adducts and some derivatives against a panel of humor tumor cell lines. A brief qualitative structure-activity relationship study indicated that carbon-carbon double bond and the presence of an electron-withdrawing substituent at the aromatic ring are essential for the activity. A quinoline-phthalide derivative has exhibited a potent effect on the proliferation of all cell lines. It is interesting to note their special cytotoxic activity against NCIADR cell line.

Phenylethylthiazolylthiourea (PETT) derivatives have been identified as a new series of nonnucleoside inhibitors of HIV-1 RT. Structure-activity relationship studies of this class of compounds resulted in the identification of N-[2-(2-pyridyl)ethyl]-N’-[2-(5-bromopyridyl)]-thiourea hydrochloride (trovirdine; LY300046.HCl) as a highly potent anti-HIV-1 agent. Trovirdine is currently in phase one clinical trials for potential use in the treatment of AIDS. Extension of these structure-activity relationship studies to identify additional compounds in this series with improved properties is ongoing. A part of this work is described here. Replacement of the two aromatic moleties of the PETT compounds by various substituted or unsubstituted heteroaromatic rings was investigated. In addition, the effects of multiple substitution in the phenyl ring were also studied. The antiviral activities were determined on wild-type and constructed mutants of HIV-1 RT and on wild-type HIV-1 and mutant viruses derived thereof, Ile100 and Cys181, in cell culture assays. Some selected compounds were determined on double- mutant viruses, HIV-1 (Ile100/Asn103) and HIV-1 (Ile100/Cys181). A number of highly potent analogs were synthesized. These compounds displayed IC50’s against wild-type RT between 0.6 and 5 nM. In cell culture, these agents inhibited wild-type HIV-1 with ED50’s between I and 5 nM in MT-4 cells. In addition, these derivatives inhibited mutant HIV-1 RT (Ile 100) with IC50’s between 20 and 50 nM and mutant HIV-1 RT (Cys 181) with IC50’s between 4 and 10 nM, and in cell culture they inhibited mutant HIV-1 (Ile100) with ED50’s between 9 and 100 nM and mutant HIV-1 (Cys181) with ED50’s between 3 and 20 nM.
