as chiral catalysts for asymmetric Michael addition reactions in the presence of an achiral additive has been tested in different solvents (CHCl3, acetone, DMF, DMSO and the room-temperature ionic liquid [bmim]PF6). The dependence of yields and enantiomeric excesses on the solvent used has been demonstrated. The experiments show that the combination of additive and peptides provides a catalytic system

The Val-Val-Tyr-Pro-Asp bone marrow peptide (MP-5) and its analogue (MP-5-Lys) were synthesized. Fluorescent derivatives, Ftc-MP-5 and MP-5-Lys(Ftc), were prepared. The iological activity of MP-5 and MP-5-Lys was studied in vitro and in vivo. The MP-5 peptide caused 60-84% inhibition of growth of the following mouse cancers: lymphatic leukemia P388, melanoma B-16, and cervical carcinoma CUC-5. These peptides also restored functional activity of T-lymphocytes that was inhibited by metabolic products of the HL-60 leukemic cell line. MP-5-Lys(Ftc) was shown to preserve the functional properties of MP-5 towards T-lymphocytes, but Ftc-MP-5 was practically inactive.
