Abstract: Antihistamines of the formula ##STR1## wherein ##STR2## is a 5 or 6 membered ring which is phenyl or heterocyclic; ##STR3## is a six membered ring which is 2,3, or 4 pyridyl or is phenyl or substituted phenyl, with the proviso that is ##STR4## is a nitrogen containing ring, ##STR5## must be phenyl; Z is an alkylene chain having 0 to 2 carbon atoms in the chain, said 2 carbon chain optionally having one double bond, said chain optionally having either a carbonyl oxygen, or a hydroxy group as a substituent; W is ##STR6## wherein p is 1 or 2 and n is 1 or 2, R.sup.1 is C.sub.1 to C.sub.6 alkyl, R.sup.2 is hydrogen or C.sub.1 to C.sub.6 alkyl, and the dotted line represents an optional double bond, R.sup.2 being absent if the double bond is present, and Y is substituted carboxylate or substituted sulfonyl. Said antihistamines have little or no sedative effects.
Abstract: There are disclosed certain alkali metal, alkaline earth metal, amine and amino acid salts of 3-(n-butyl)-4-hydroxy-1-phenyl-1,8-naphthyridine-2(1H)-one which, unlike the parent compound, are useful for orally treating chronic obstructive lung diseases such as asthma, bronchitis and the like.
Abstract: Disclosed is an improved process for the synthesis of 6-bromo-17,21-dihydroxy-3,11,20-trioxo-1,4,-pregnadienes 17,21-diesters. In particular, this invention relates to the conversion of 17,21-dihydroxy-3,11,20-trioxo-1,4-pregnadienes 17,21-diesters to 6-borom-17,21-dihyroxy-3,11,20-trioxo-1,4-pregnadienes-17-21-diesters via bromination under ionic conditions, e.g. bromine in acetic acid.
