A diastereo- and enantioselective propargylic substitution reaction between propargylic carbonates and α-substituted nitroacetates catalyzed by a Cu-pybox complex is described. This method allows the preparation of a series of non-proteinogenic quaternary α-aminoacid precursors featuring two contiguous stereogenic centers and a terminal alkyne moiety in high yields with good to excellent diastereo-
The invention relates to a pharmaceutical composition comprising an apoptosis-inducing amount of a compound having general formula (I), wherein: (i) R1 represents an unsubstituted C6 or C10 aryl group; or a C6 aryl group substituted with Me or OMe; (ii) A represents O, S or S partially oxidized to sulfoxide; (iii) the cyclic group labelled F represents an unsubstituted C6 or C10 aryl-fused group or a C5 heteroaryl-fused group (nitrogen as heteroatom) or a benzo-fused system substituted with ethoxycarbonyl function; (iv) and Y represents the group (A) wherein R2 and R3 are independently hydrogen; or methyl; or Y represents the group CH3 or a (CH2)2CH3 group; or an unsubstituted C5 heteroaryl group (nitrogen as heteroatom). The compositions may be used for the treatment of tumours or other cancerous conditions, such as CML (chronic myeloid leukaemia), AML, in AIDS-related lymphomas (such as Karpowski's sarcoma, a sub-cutaneous lymphoma) and used as apoptotic agents in the treatment of cancers generally.

Previously we described a series of 5-acylaminobenzophenones with considerable antimalarial activity. Unfortunately, most compounds also displayed high cytotoxicity resulting in low selectivity towards malaria parasites. Through the replacement of the 5-acylamino moiety by simple chlorine and further modifications of the 2-acylamino residue we could obtain inhibitors with improved selectivity towards malaria parasites combined with an acceptable reduction of antimalarial activity.
