The preparation of 2-(1,3-diazacycloalkenyl)-2-hydrazones of 1-(substituted 2-benzofuranyl)-3-(substituted aryl)-2-propen-1-ones is described. These compounds are useful as anti-tubercular agents in warm blooded animals.
A new and distinct
Paeonia
cultivar named ‘RTPIV791-01’ is disclosed, characterized by distinctive creamy pale yellow suffused with pink, fully double, mildly fragrant flowers. Plants are vigorous and symmetrical with strong stems holding flowers above foliage, and with attractive foliage through the Fall. The new cultivar is a
Paeonia
hybrid suitable for ornamental garden purposes.

The synthesis of a series of substituted 6,7-dihydroimidazo[1,2-a]purin-9(4H)-ones is described. Several members of the series exhibit enhanced antiallergic and bronchodilator activity and reduced side effects as compared to theophylline. Structure-activity relationships and metabolic considerations are discussed for the series. Analogues substituted with a 4-(4-chlorobenzyl) moiety, such as 33 and 40, shown an optimal balance of antiallergic and bronchodilator activity and are of particular interest. Compound 33 is significantly more potent than theophylline against both metacholine- and antigen-induced bronchospasms, does not affect spontaneous motor activity, and shows minimal cardiovascular effects in the rat.
