Studies of arylthiazole oxamates in relation to oral antiallergic activity

25 arylthiazole oxamate derivatives were synthesized and examined for antiallergic activity in the rat passive cutaneous anaphylaxis assay. These compounds were prepared by treatment of the appropriate bromoacetophenone with thioureas to give arylaminothiazoles. Further condensation with alkyloxalyl chloride gave the arylthiazolyl oxamates. Several derivatives showed a 70% inhibition at 5 mg/kg p.o. p-Alkoxy substitution on the phenyl ring resulted in enhanced activity while N-alkyl substitution on the nitrogen amide function inhibited the activity. Ethyl-N-(4-p-methoxyphenyl)-2-thiazolyl oxamate (tioxamast, F-1865) was selected for clinical studies.

Solution phase synthesis of a spiro[pyrrolidine-2,3′-oxindole] library via a three component 1,3-dipolar cycloaddition reaction

A combinatorial library of 26,500 spiro[pyrrolidine,-2,3-oxindoles] was prepared in a single-compound format by a facile intermolecular 1,3-dipolar cycloaddition. An azomethine ylide, generated by the decarboxylative condensation of an isatin 1 with an alpha-amino acid 2, was trapped by a transchalcone 3 to afford heterocycles of the general structure 4. The regio- and stereochemistry of a representative product was determined by single crystal X-ray structure.

Discovery of 6-substituted 4-anilinoquinazolines with dioxygenated rings as novel EGFR tyrosine kinase inhibitors

It had been reported that some dioxygenated rings fusing with the quinazoline scaffold could lead to new EGFR inhibitors. Based on this, several kinds of oxygenated alkane quinazoline derivatives were synthetized and evaluated as EGFR inhibitors. Their antiproliferative activities were tested against four cancer cell lines: A431, MCF-7, A549, and B16-F10. Most derivatives could counteract EGF-induced EGFR phosphorylation, and their potency was comparable to the reference compound Erlotinib. The size of the fused dioxygenated ring was crucial for the biological activity and the heptatomic ring derivative 19 showed potent in vitro inhibitory activity in the enzymatic assay as well as in the cellular assay.

Diverse reactivity in microwave-promoted catalyst-free coupling of substituted anilines with ethyl trifluoropyruvate and biological evaluation

Diverse reactivity by coupling of substituted anilines with ethyl trifluoropyruvate was developed under microwave irradiation without catalysts to generate 3-trifluoromethyl-3-hydroxy oxindoles, aromatic hydroxy trifluoromethyl esters, and 1,2-dicarbonyl compounds in a fast and efficient manner. The plausible mechanism for obtaining different products was proposed. Furthermore, the anti-HIV activity of aromatic hydroxy trifluoromethyl esters was first reported. The best inhibitory activity against wild-type HIV-1 IIIB was exemplified by trifluoromethyloxindole 3q with an IC50 = 5.8 muM, which also displayed potential activity against Y181C mutant virus with an IC50 = 7.5 muM. More significantly, the activities of oxindoles 3q and 3r to inhibit K103N/Y181C double mutant HIV-1 reverse transcriptase (RT) are probably similar to that of the second-generation nonnucleoside inhibitor HBY 097 by docking calculation.

Silver-catalyzed decarboxylative alkynylation of aliphatic carboxylic acids in aqueous solution

C(sp3)-C(sp) bond formations are of immense interest in chemistry and material sciences. We report herein a convenient, radical-mediated and catalytic method for C(sp3)-C(sp) cross-coupling. Thus, with AgNO3 as the catalyst and K2S2O8 as the oxidant, various aliphatic carboxylic acids underwent decarboxylative alkynylation with commercially available ethynylbenziodoxolones in aqueous solution under mild conditions. This site-specific alkynylation is not only general and efficient but also functional group compatible. In addition, it exhibits remarkable chemo- and stereoselectivity.
