    The preparations of a series of thiazolo[4,5-b]pyrazines by ring closure of 3-aminopyrazine-2-thiols with orthoesters, and potassium ethyl xanthate are described. 2-Amino-5-bromopyrazine-3-thiol with potassium ethyl xanthate gave both 6-bromothiazolo[4,5-b]pyrazine-2-thiol and thiazolo[4,5-b]- pyrazine-2,6-dithiol. Various S-alkyl derivatives are reported. As amplifiers of phleomycin, 2-(5,6-dimethylthiazolo[4,5-b]pyrazin-2-yltho)- NN-dimethylethylamine, 2-6- (2-dimethylamino- ethylthio)thiazolo[4,5-b]pyrazin-2-ylthio)-N,N-dimethylethylamine, and N,N-dimethyl-2-(2-methyl- thiazolo[4,5-b]pyrazin-6-ylthio)ethylamine each showed moderate activity.

    Derivatives of the thiazolo[4,5-b]pyrazine system are reported including those with 2-phenyl substituents or fused benzene rings (as in thiazolo[4,5-b]quinoxalines) together with strongly basic N,N-dimethylaminoethylthio or N,N-dimethylaminopropylthio side chains. Series of thiazolo[4,5-c]- pyridines, thiazolo[5,4-b]pyridines and quinoxalines are also described. A new process for the preparation of 3-N,N-dimethylaminopropylthio derivatives of heterocycles by reaction of the mercapto compound with 3-chloro-N,N-dimethylpropylamine in ethanolic ammonia has been shown to give more reliable and improved results. Of the compounds examined for amplification of the activity of phleomycin, N,N-dimethyl- 3-(2-methylthiazolo[4,5-pyrazin-6-ylthio)propylamine and 3-[3-(3-N,N-dimethylaminopropylthio)- quinoxalin-2-ylthiol-N,N-dimethylpropylamine were the best, and showed four star activity at 1 mM and 0.5 mM respectively. A 2-phenyl substituent in, or a benzene ring fused to, thiazolo[4,5-b]- pyrazines did not increase amplification. The 2-substituted thiazolo[4,5-c]pyridines showed activity comparable to that of the 2-substituted thiazolo[4,5-blpyrazines whereas that of the thiazolo[5,4-b]pyrazines was lower.

    据报道,噻唑并[4,5-b]吡嗪系统的衍生物包括以下几种 (如噻唑并[4,5-b]喹喔啉)以及强碱性 N,N-二甲氨基基或 N,N-二甲氨基丙硫基侧链。 侧链。此外,还介绍了噻唑并[4,5-c]吡啶噻唑并[5,4-b]吡啶喹喔啉系列。 系列。制备 3-N,N-二甲氨基丙硫基杂环衍生物的新工艺 巯基化合物与 3--N,N-二甲基丙胺乙醇中的反应 在乙醇中的反应,结果更可靠、更有效。 在研究过的能增强新霉素活性的化合物中,N,N-二甲基- 3-(2-甲基噻吩) 3-(2-甲基噻唑并[4,5-吡嗪-6-基基)丙胺 和 3-[3-(3-N,N-二甲基丙硫基)-喹喔啉-2-基基]的活性。 喹喔啉-2-醇-N,N-二甲基丙胺的活性最好,在 1 mM 和 0 mM 浓度下显示出四星级活性。 星级活性,浓度分别为 1 毫摩尔和 0.5 毫摩尔。 分别显示出四星级活性。噻唑并[4,5-b]-吡嗪中的 2-苯基取代基或苯环与噻唑并[4,5-b]-吡嗪融合并不能提高扩增率。 并不增加扩增。2 取代的噻唑并[4,5-c]吡啶 的活性与 2-取代的噻唑并[4,5-b]吡嗪的活性相当。 而噻唑并[5,4-b]吡嗪的活性较低。

    Tetraaza benzoxazinophenothiazine heterocyclic rings were synthesized and characterized. The key intermediate, 11-amino-6-chlorobenzo[a]-8,10-diazaphenoxazin-5-one was prepared by reaction of 4,5-diamino-6-hydroxypyimidine with 2,3-dichloro-1,4-naphthoquinone in anhydrous sodium carbonate. Whereas the parent tetraaza derivatives: 15-amino-8-bromo-6,9,12,14-tetraazabenzo[a][1,4]benzoxazino[3,2-c] phenothiazine, 9,15-diamino-6,8,12,14-tetraazabenzo[a][1,4]benzoxazino[3,2-c]pheno- thiazine and 15-amino-6,8,12,14-tetraazabenzo[a][1,4]benzoxazino[3,2-c]phenothiazine were synthesized by base catalyzed  condensation reactions of 11-amino-6-chlorobenzo[a]-8,10-diazaphenoxazin-5-one with 2-amino-5-bromopyrazin-3-thiol, 4,6-diaminopyrimidine-5-thiol and 4-diaminopyrimidine-5-thiol respectively. The compounds are intensely coloured and are readily reduced with sodium dithionite to their leuco bases which can make them applicable as vat dyes.  Their wash fastness, sublimation fastness and staining undyed fabric were evaluated.

    Isomeric derivatives of angular aza benzophenothiazine and complex aza benzothiazinophenothiazine rings were successfully synthesized. Reactions of 2-amino-3,5-dibromopyrazine with 6,7-dibromoquinoline-5,8-dione in anhydrous sodium carbonate gave isomeric angular aza benzophenothiazine compounds 6,9-dibromo-1,8,11-triazabenzo[a]phenothiazine-5-one and 6,9-dibromo-4,8,11-triazabenzo[a]phenothiazine-5-one. Further reactions of these compounds, in the first case, respectively with 2-amino-6-methoxypyridin-3-thiol gave the two isomeric aza complex compounds identified as 13-bromo-8-methoxy-1,9,12,15-tetraazabenzo[a][1,4]benzothiazino[3,2-c]phenothiazine and 13-bromo-8-methoxy-4,9,12,15-tetraazabenzo[a][1,4]benzothiazino[3,2-c]phenothiazine. Secondly, reactions of the same angular benzophenothiazine compounds with 4-aminopyrimidin-5-thiol gave two more complex compounds 13-bromo-1,6,8,12,15-pentaazabenzo[a][1,4]benzothiazino[3,2-c]phenothiazine and 13-bromo-4,6,8,12,15-tetraazabenzo[a][1,4]benzothiazino[3,2-c]phenothiazine.  The compounds have very intense colours.
