The present invention comprises a compound of formula I: ##STR1## R.sub.1 of Formula I is substituted amino represented by formula NR.sup.5 R.sup.6 wherein R.sup.5 and R.sup.6 are independently selected from the group consisting of hydrogen, C.sub.1-4 alkyl, and unsubstituted amino with the proviso that R.sup.5 and R.sup.6 are not both hydrogen, and further that R.sup.5 and R.sup.6 are not both amino. R.sub.2 and R.sub.3 of Formula I are independently selected from the group consisting of hydrogen; C.sub.1-4 alkyl; amino; substituted or unsubstituted thiol; and halogen. Moreover, R.sub.4 of Formula I is represented by the formula R.sup.12 -X.sup.12 wherein R.sup.12 is a saturated or unsaturated linear hydrocarbon chain of 5-20 carbons optionally containing one or more interruptions within the chain by a heteroatom, and optionally substituted with one or more .dbd.O, or .dbd.S. Finally, X.sup.12 is selected from the group consisting of hydroxy, an aminoalkyl group, and a known amino acid bound by its .alpha.-amino group.
本发明涉及一种化合物,其化学式为I:##STR1## 其中,公式I中的R.sub.1是由公式NR.sup.5 R.sup.6表示的取代氨基,其中R.sup.5和R.sup.6分别选自氢、C.sub.1-4烷基和未取代氨基的群体,但要求R.sup.5和R.sup.6不能同时为氢,并且R.sup.5和R.sup.6不能同时为氨基。公式I中的R.sub.2和R.sub.3分别选自氢、C.sub.1-4烷基、氨基、取代或未取代硫醇和卤素的群体。此外,公式I中的R.sub.4由公式R.sup.12-X.sup.12表示,其中R.sup.12是一个5-20个碳原子的饱和或不饱和线性碳氢链,可选地在链中由杂原子插入,并可选地取代一个或多个.dbd.O或.dbd.S。最后,X.sup.12选自羟基、氨基烷基和已知氨基酸的.alpha.-氨基结合。
