9H-xanthen-9-amines possessing a wide variety of nitrogensubstituents at C-9 was prepared for evaluation of gastric antisecretory activity. These substituents included the acetamidine, imidate, pyrimidine, thiazoline, quinuclidine, 2-hydrazinopyridine, aminopiperidine, aminoalkylimidazole, and aminoalkylpyridine moieties. The majority of compounds in this series inhibited gastric acid secretion when tested orally in
Novel compounds, their salts and compositions related thereto having activity against mammalian factor Xa are disclosed. The compounds are useful in vitro or in vivo for preventing or treating coagulation disorders.

This invention relates to compositions containing a sulfur containing antiwear/extreme pressure agent, basic nitrogen compound or a mixture thereof together with a hydrocarbyl mercaptan. The composition may additionally contain a phosphorus or boron antiwear or extreme pressure agent, a dispersant or an overbased metal salt. The invention also relates to lubricants, functional fluids, and concentrates containing the same. Seals, e.g. nitrile, polyacrylate, and fluoroelastomer, in contact with these composition have reduced deterioration. With the use of these compositions, lubricants, and functional fluids, the seals' useful life is extended.
