Abstract

Abstract Novel heteroarotinoid compositions characterized by the formulae: ##STR1## where R is H, CH 3 or C 2 H 5 and X is S, S O, O, NCH 3 , Si(CH 3 ) 2 , N + (H)CH 3 [Cl - ], N + (H)CH 3 [Br - ] or N + (alkyl) CH 3 [Cl - or Br - ) where alkyl is CH 3 , C 2 H 5 , CH 2 ═CHCH 2 or C 6 H 5 CH 2 . Such compositions exhibit activity as anticancer agents.
