Compounds of the saframycin-ecteinascidin series with cytotoxic properties having the general formula (1), their uses and synthesis, are disclosed. In said formula, R1 and R4 is H, a C1 to C4 alkyl group, or an acyl group; R2 i s an ether, ester, amide, or a phthalimide group; R3 is =O, OH, an ether group , an acyl group such as OC(O)Me, OC(O)Bn and OC(O)Et, or a sulfide group; R5 i s H, halogen, OH, an ether group, an acyl group, or an amide group; R6 is =O, OH, OCH3, CN, or an acyfoxy group; wherein R7 is =0, OH, halogen, an ether group, or an acyl group; wherein R8 and R9 are independently H, CH3, OCH3 OC2H5, CF3, halogen such as Br and F, or R8 and R9 are joined together as a methylenedioxy group, or other five or six membered ring; R10 and R11 are independently CH3, OCH3, OC2H5, SCH3, or SC2H5; R12 is H, a C1 to C4 alkyl group, or an acyl group; and the chiral center marked * has the R or the S configuration.
