The present invention provides
17-Iminomethylalkenyl- and 17-iminoalkyl-14β-hydroxy-5β-androstane derivatives of general formula (I):
wherein:
the symbol means a or configuration or a Z or E configuration;
A represents (CH2)m or -(CH = CH)n-;
m represents an integer number from 1 to 6;
n represents an integer number from 1 to 3.
R1 represents hydrogen, C2-C4 alkyl unsubstituted or substituted by NR4R5 wherein R4, R5 which may be the same or different, represent hydrogen, C1-C4 alkyl or R4 and R5 may form, taken together with the nitrogen atom, a five- or six-membered heterocyclic ring optionally containing one or more further heteroatoms selected from oxygen and nitrogen;
R2 represents hydrogen or hydroxy;
R3 represents NHC(=X)NR6Ry or OR8 wherein
R6, R7 which may be the same or different, represent hydrogen, methyl or C2-C4 alkyl unsubstituted or substituted by NR4 R5 wherein R4 and R5 have the previously defined meanings;
R8 represents hydrogen; methyl; C2-C6 alkyl, unsubstituted or substituted by one or more NR4R5 or NHC(=NH)NH2, wherein R4 and R5 have the previously defined meanings;
X represents O, S or NR9;
R9 represents hydrogen, methyl, C2-C4 alkyl, C2-C4 acyl or phenyl, where the C2-C4 alkyl, C2-C4 acyl are unsubstituted or substituted by NR4 R5, wherein R4 and R5 have the previously defined meanings; and
R6, R7, R9 taken two by two may form, together with the heteroatoms they are linked to, and where possible, a five- or six- or seven-membered heterocyclic ring.
