The present invention provides triphenylphosphonium biguanide analogs of general formula (I), whereas the general formula (I) includes resonance structures and pharmaceutically acceptable salts, protonated form as well as free base, (Formula (I)) where each one of R1, R2, R3, R4, R5, R6, R7 is independently selected from the group comprising H; C1-C6 alkyl; C6-C10 aryl; (C1-C6)alkyl(C6-C10)aryl; -C(=O)-R'; -C(=O)OR'; -C(=O)NR'R"; -C(=S)R'; -C(=S)NR'R''; wherein R' and R" are independently selected from the group comprising H, C1-C6 alkoxy, C1-C6 alkyl, C6-C10aryl, (Cl-C6)alkyl(C6-C10)aryl; whereas C1-C6 alkoxy, C1-C6 alkyl, C6-C10 aryl, (C1-C6)alkyl(C6-C10)aryl can be unsubstituted or substituted by one or more substituents selected independently from the group comprising C1-C4 alkyl, N(H or C1-C4 alkyl)2, wherein alkyls are the same or different, phenyl, benzyl, OH, SH, F, CI, Br, I, C1-C4alkoxy, C1-C4 acyloxy, C1-C4 mercapto; and substituent of general formula (II) (Formula (I)) wherein Z is as defined in the claims, whereas at least one of R1, R2, R3, R4, R5, R6, R7 is the substituent of general formula (II), X- is a pharmaceutically acceptable anion, preferably an anion of inorganic or organic acid, Y- is a pharmaceutically acceptable anion, preferably an anion of inorganic or organic acid. The invention further provides a method of preparation of these derivatives. These new compounds are suitable in particular for the treatment of diabetes mellitus type 2 and/or pancreatic carcinoma.
