This invention provides antiviral pyridazinyl hydrazones of the formula ##STR1## wherein when taken singly, R is H, CH.sub.3 or C.sub.2 H.sub.5 ; and R.sup.1 is thienyl, halothienyl, pyridyl, methylthienyl, furyl, indolyl, tolyl, xylyl, biphenyl, C.sub.1 -C.sub.4 alkoxyphenyl, 1-adamantyl and, when R is other than H, methyl; R and R.sup.1 taken together form a 2-adamantindinyl group; and R.sup.3 is a C.sub.4 -C.sub.6 tertiary alkyl group attached through a tertiary carbon to the pyridazine ring, such as t-butyl, 1,1-dimethylethyl, 1,1-dimethylpropyl, or 1-methyl-1-ethylpropyl, and mineral acid addition salts thereof.
本发明提供了式为##STR1##的抗病毒吡啶肼类化合物,其中当单独取时,R为H,CH.sub.3或C.sub.2H.sub.5;R.sup.1为噻吩基、卤代噻吩基、吡啶基、甲基噻吩基、呋喃基、吲哚基、甲苯基、二甲苯基、联苯基、C.sub.1-C.sub.4烷氧基苯基、1-金刚烷基,当R不为H时,R和R.sup.1结合形成2-金刚烷基吲哚基;R.sup.3是通过三级碳原子连接到吡啶肼环的C.sub.4-C.sub.6三级烷基,例如叔丁基、1,1-二甲基乙基、1,1-二甲基丙基或1-甲基-1-乙基丙基,以及其矿酸盐。
