number of N-alkylazacycloheptan-2-onederivatives, with the hydrocarbon chain lengths systematically varied from C2 to C16, were tested for their possible skintoxic effects. For this purpose, three in vitro cytotoxicity assays were used: (1) inhibition of proliferation of culturedhuman fibroblasts and keratinocytes; (2) inhibition of collagen contraction by human fibroblasts; and (3) cell morphology
Compositions useful for carrying physiologically active agents such as therapeutic agents through skin and other body membranes comprising the agent and an effective, non-toxic amount of a compound having the structural formula ##STR1## wherein R' is H or a lower alkyl group, m is 3-7, N is 0-17 and R is --CH.sub.3, phenyl or substituted phenyl or ##STR2## with the proviso that if m is 3 and R is --CH.sub.3, then n is not 0-6.
