title: Studies on aziridine derivatives. III. Synthesis and immunopharmacological activity of aziridine derivatives of propionic acid.
abstract: Several new aziridine derivatives of propionic acid were synthesized (10-15, 19, 20). o-, m-, p-Chloroanilide of chloroacetic acid 1-3 and chloride of 3-/p-chlorobenzoyl/acrylic acid 16 were the substrates. The compounds 1-3 in reaction with nicotine aldehyde or p-chlorobenzaldehyde were transformed into appropriate anilides of 2,3-epoxypropionic acid 4-9. These, in turn reacted with ethylenimine giving the appropriate 3-aziridine derivatives 10-15. Acid chloride 16 in reaction with amines gave the appropriate amides 17 and 18 which formed 2-aziridine derivatives 19 and 20 when under the influence of ethylenimine. Pharmacological analysis revealed that the aziridine derivatives 12-15, 19 and 20 modulate some immunological reactions with the prevailing effect of the suppressive component (PFC, RFC, IgM level, cellular response to SRBC). The stimulatory effect was observed with some compounds on the level of circulating IgG and GvH reaction. The mechanism of these compounds consists in their interference with the activity of Ts cells and mediators of the immunological reactions.
