A series of 9-[(aminoalkyl)thio]-9H-xanthenes (3-6) and 5-[(aminoalkyl)thio]-5H-[1]benzopyrano[2,3-b]pyridines (7-10) possessing gastricantisecretory activity in the rat and dog is described Many of the compounds possessed good activity in the pylorus-ligated rat and several inhibited histamine-stimulated gastric acid secretion in the dog. The mechanism of acid secretion inhibition is not related
A curable composition comprising a liquid base polymer, a silicone elastomer powder, and a crosslinking agent is in putty form prior to curing, tack-free to the hand, easy to work, and adherent.
An inorganic filler which has been surface coated with an addition cure silicone composition in the cured state is included in an organopolysiloxane composition, which becomes effective for preventing the filler from settling down even during long-term shelf storage.

An organopolysiloxane composition comprising 0.01% to less than 0.5% by weight of a sulfidable metal powder is provided. When a silver-containing precision electronic part is encapsulated or sealed with the cured composition, the metal powder in the cured composition is sulfided with sulfur-containing gas for thereby preventing or retarding the corrosion of the electronic part with the sulfur-containing gas.
