Invention concerning the therapeutic use of tetracyclic derivatives and their pharmaceutically acceptable salts having the following general formula: ##STR1## in which, independently of the other: X is a carbon or nitrogen atom, T is a carbon or nitrogen atom, L is an oxygen atom or ketone functional protective group, R.sub.1 is an atom of hydrogen, an atom of halogen, or a C.sub.1 to C.sub.5 alkyl radical, R.sub.2 is a hydrogen atom, a halogen atom, a nitro radical, or a C.sub.1 to C.sub.5 alkyl radical, n and m are equal to 0 or to 1, but not independently of the other, so that if n is equal to 1, then m is equal to 0, and if n is equal to 0, then m is equal to 1.
有关四环类衍生物及其药用可接受盐的治疗用途的发明,其具有以下一般公式:##STR1## 其中,独立于其他:X为碳或氮原子,T为碳或氮原子,L为氧原子或酮官能团保护基团,R.sub.1为氢原子、卤素原子或C.sub.1至C.sub.5烷基基团,R.sub.2为氢原子、卤素原子、硝基基团或C.sub.1至C.sub.5烷基基团,n和m等于0或1,但不独立于其他,因此如果n等于1,则m等于0,如果n等于0,则m等于1。
