A series of N-substituted 2-mercaptoacetamidines was synthesized and evaluated for gastricantisecretory activity in dogs stimulated with gastrin tetrapeptide. The most potent analogues showed 80--95% inhibition of acid secretion after an oral dose of 8 mg/kg. Thus, these compounds represent a new structural type having significant antisecretory activity. Disulfides had essentially the same antisecretory

A method for initiating and bonding thin films on substrates is described. The method employs an interlayer comprising a self-assembling monolayer (SAM). The SAM is formed from monomers, one end of which are capable of bonding to the substrate, and the other end of which form a surface similar to, and capable of initiating the formation of a film.
Additionally, compositions for monomers, methods for SAM formation, and methods for film formation are disclosed. In a preferred embodiment the thin film is comprised of diamond.
