The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 4-Methyl-6-(methylthio)pyrimidin-2-ol( cas:16710-11-5 ) is researched.Application In Synthesis of 4-Methyl-6-(methylthio)pyrimidin-2-ol.Felczak, Krzysztof; Drabikowska, Alicja; Vilpo, Juhani A.; Kulikowski, Tadeusz; Shugar, David published the article 《6-Substituted and 5,6-Disubstituted Derivatives of Uridine: Stereoselective Synthesis, Interaction with Uridine Phosphorylase, and in Vitro Antitumor Activity》 about this compound( cas:16710-11-5 ) in Journal of Medicinal Chemistry. Keywords: structure activity nucleoside antitumor phosphorylase substrate; uridine preparation antitumor cytotoxicity phosphorylase substrate; nucleoside preparation antitumor cytotoxicity phosphorylase substrate. Let’s learn more about this compound (cas:16710-11-5).
Stereoselective procedures are described for the synthesis of 6-alkyluridines, e.g. I (R = F, OH, R1 = H, F), by Lewis acid-catalyzed condensation of trimethylsilylated 6-alkyl-4-alkylthiouracils with 1-O-acetyl-2,3,5-tri-O-benzoyl-β-D-ribofuranose (ABR) and trimethylsilylated 6-alkyl-3-benzyluracils with ABR. For all the foregoing nucleosides in the fixed syn conformation about the glycosyl bond, 1H NMR spectroscopy further demonstrated that the pentose rings exist predominantly in the conformation N (3′-endo). Most of the nucleosides were weak substrates of Escherichia coli pyrimidine nucleoside phosphorylase. The 5-fluoro-6-substituted uridines were the poorest substrates. Cytotoxicities of the nucleosides were examined vs the human tumor cell lines MOLT-3, U-937, K-562, and IM-9, as well as PHA-stimulated human lymphocytes. Two of the analogs, 5-fluoro-6-(fluoromethyl)uridine and 5-fluoro-6-(hydroxymethyl)uridine, exhibited cytotoxicities comparable to that of 5-fluorouracil.
Although many compounds look similar to this compound(16710-11-5)Application In Synthesis of 4-Methyl-6-(methylthio)pyrimidin-2-ol, numerous studies have shown that this compound(SMILES:CSC1=NC(O)=NC(C)=C1), has unique advantages.
