Heterocyclic guanidine derivatives of the formula:
in which D is O, S or NH; E is CH or when D is O or S, E is N; Y is S, O, CH2, SO or a direct bond; P is a direct bond or C(1-4)unbranched alkylene optionally substituted by 1 or 2 C(1-4)alkyls and Q is C(1-4)unbranched alkylene optionally substituted by 1 or 2 C(1-4)alkyls, provided total number of alkyls in P and Q is 1 or 2, that when Y is S, 0 or SO, P is alkylene and that when Y is O or SO, Q is C(2-4)alkylene; R1 is H or C(1-10)alkyl; A is 3,4-dioxocyclo- buten-1,2-diyl or C=Z where Z is S, O, NCN, NNO2, CHNO2, NCONH2, C(CN)2, NCOR2, NCO2R2, NSO2R2 or NR3 where R3 is C(1-6)alkyl or C(6-12)aryl and R3 is H or C(1-6)alkyl; B is C(1-6)alkoxy, C(1-6)alkylthio or NR4R5 where R4 and R5 are H, C(1-10)alkyl, C(3-6)alkenyl, C(3-6)alkynyl, C(2-6)(primary,OH)alkyl, C(2-6)primary NH2)alkyl, C(3-6)cycloalkyl, or R4 and R5 together are a 5- or 6-membered saturated ring which may contain an additional O or NH: and the salts thereof. A process for the manufacture of said compounds is described; e.g. 2-guanidino-4-(5-amino-2-methylpentyl)-thiazole gives by reaction with dimethyl(cyanimido)dithio- carbonate and then methylamine 2-guanidino-4-[5-(2-cyano-3-methylguanidino)-2-methylpentyl]thiazole.
式中的杂环胍衍生物:
其中 D 是 O、S 或 NH;E 是 CH 或当 D 是 O 或 S 时,E 是 N;Y 是 S、O、CH2、SO 或直接键;P 是直接键或任选被 1 或 2 个 C(1-4)烷基取代的 C(1-4)未支链亚烷基,Q 是任选被 1 或 2 个 C(1-4)烷基取代的 C(1-4)未支链亚烷基,条件是 P 和 Q 中的烷基总数是 1 或 2,当 Y 是 S、0 或 SO 时,P 是亚烷基,当 Y 是 O 或 SO 时,Q 是 C(2-4)亚烷基;R1 是 H 或 C(1-10)烷基;A 是 3,4-二氧代环丁烯-1,2-二基或 C=Z 其中 Z 是 S、O、NCN、NNO2、CHNO2、NCONH2、C(CN)2、NCOR2、NCO2R2、NSO2R2 或 NR3,其中 R3 是 C(1-6)烷基或 C(6-12)芳基,R3 是 H 或 C(1-6)烷基;B 是 C(1-6)烷氧基、C(1-6)烷硫基或 NR4R5,其中 R4 和 R5 是 H、C(1-10)烷基、C(3-6)烯基、C(3-6)炔基、C(2-6)(伯,OH)烷基、C(2-6)伯 NH2)烷基、C(3-6)环烷基,或 R4 和 R5 合在一起是一个 5 或 6 元饱和环,其中可能含有一个额外的 O 或 NH:及其盐类。描述了制造上述化合物的工艺,例如 2-胍基-4-(5-氨基-2-甲基戊基)-噻唑通过与二甲基(氰基氨基)二硫代碳酸酯反应,然后与甲胺反应得到 2-胍基-4-[5-(2-氰基-3-甲基胍基)-2-甲基戊基]噻唑。
