A peripheral benzodiazepine receptor (PBR) ligand (TZ6, 5) has been selected as receptor-mediated carrier for antitumor cisplatin-like compounds. Compound 5, containing a thiazole ring in position 2 of the imidazopyridine nucleus, is able to act as a dinitrogen chelate toward platinum. The resulting complex, cis-[PtCl2(5)], that is, compound 8, has been fully characterized by NMR techniques and has been shown to possess affinity and selectivity for the PBR comparable to those of 5 (IC50 of 4.6 and 2.81 nM for 8 and 5, respectively; selectivity indexes for PBR greater than 10 000 for both compounds). Hence, a platinum moiety cross-linking the imidazopyridine and the thiazole aromatic rings does not alter the affinity for PBR. The same cross-linking could be responsible for the tendency of 8 to associate in dimers. The equilibrium between monomer and dimer has been investigated by NMR spectroscopy and the corresponding constant determined.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 79265-30-8, Name is 2-(Trimethylsilyl)thiazole, molecular formula is C6H11NSSi.

The detoxification of the phytoalexin brassinin to indole-3-carboxaldehyde and S-methyl dithiocarbamate is catalyzed by brassinin oxidase (BOLm), an inducible fungal enzyme produced by the plant pathogen Leptosphaeria maculans. Twenty-six substituted quinolines and isoquinolines are synthesized and evaluated for antifungal activity against L. maculans and inhibition of BOLm. Eleven compounds that inhibit BOLm activity are reported, of which 3-ethyl-6-phenylquinoline displays the highest inhibitory effect. In general, substituted 3-phenylquinolines show significantly higher inhibitory activities than the corresponding 2-phenylquinolines. Overall, these results indicate that the quinoline scaffold is a good lead to design paldoxins (phytoalexin detoxification inhibitors) that inhibit the detoxification of brassinin by L. maculans.

Ro 31-8959 (1), a potent and selective inhibitor of HIV proteinase, is currently in phase III clinical trials.Six approaches for the large-scale synthesis of this compound have been studied.All routes employ an initial disconnection to an electrophilic L-phenylalanine homologue equivalent 13 and the decahydroisoquinoline derivative 5.They differ in adopting either an epoxide, a cyclic sulfate, or an aldehyde as the electrophilic entity and develop chirality from L-phenylalanine, dimethyl D-tartrate, or a Sharpless epoxidation.The preferred route starts from N-phthaloyl-L-phenylalaninyl chloride and uses tris((trimethylsilyl)oxy)ethene to effect homologation to hydroxy ketone 30, which is elaborated in a five-step two-pot procedure to N-phthaloyl epoxide 33 and hence 1.Kilogram quantities of Ro 31-8959 have been prepared using this route.

[structure: see text]. An efficient and highly stereoselective synthesis of the gastroprotective natural product AI-77-B is described. The stereocenters of the hydroxy amino acid moiety were generated by an ester-derived titanium-enolate-mediated syn-aldol reaction, a Curtius rearrangement, and application of Dondoni’s aldehyde homologation. Condensation with the dihydroisocoumarin fragment and subsequent deprotecting transformations furnished optically active AI-77-B.

Described herein is the synthesis of 3-C-carboxy-5-deoxy-L-xylose (aceric acid), a rare branched-chain sugar found in the complex pectic polysaccharide rhamnogalacturonan-II. The key synthetic step in the construction of aceric acid was the stereoselective addition of 2-trimethylsilyl thiazole to 5-deoxy-1,2-O-isopropylidene-alpha-L-erythro-pentofuran-3-ulose (2), which was prepared from L-xylose. The thiazole group was efficiently converted into the required carboxyl group via conventional transformations. Aceric acid was also synthesized by dihydroxylation of a 3-C-methylene derivative of 2 followed by oxidation of the resulting hydroxylmethyl group. The C-2 epimer of aceric acid was also synthesized using thiazole addition chemistry, starting from L-arabinose.
