Abstract
In order to identify a pair of neuroleptic enantiomers with the highest stereoselective interaction with neuroleptic/dopamine receptors, the effects of eight pairs of neuroleptic enantiomers were tested on the specific binding of 3H-spiperone to crude homogenates of calf caudate nucleus. The ratios of the Ki values were: (+)-butaclamol/(-)-butaclamol = 3000; dexclamol/(-)-analogue = 151; (+)-isobutaclamol/(-)-isobutaclamol = 146; (-)-CTC/(+)-CTC= 109; (-)-centbutindole/(+)-centbutindole = 20; S(+)-octoclothepin/R(-)-octoclothepin = 11. Thus, the neuroleptic receptor is highly stereoselective for the rigid butaclamol derivatives, but much less so for the flexible neuroleptics. The 3H-apomorphine binding site, however, had a stereoselectivity ratio of only 7 for isobutaclamol, further suggesting that the high affinity sites (i.e. nM) for 3H-neuroleptic binding and for 3H-apomorphine binding are different.

Abstract
Synthesis and antiimplantation activity of variously substituted 2,2-dialkyl-3,4-diphenylchromenes and 3,4-cis- and trans-chromans derived from them are described. Pregnancy-inhibiting activity in rats was exhibited by a number of these compounds, which was particularly marked in the case of 3,4-trans-3-phenyl-4-p-(beta-pyrrolidinoethoxy)-phenyl-7-methoxychroman (32), the corresponding 2,2-dimethyl analog 34, and 3-phenyl-4-p-(beta-pyrrolidinoethoxy)phenyl-7-methoxychromene (26). The structure-activity relationship of these compounds is discussed.

Abstract
1,3,8-Triazabicyclo[4.4.0]decan-2-ones and -thiones varying substituents at positions 3 and 8 have been synthesized. When tested in cotton rats for their antifilarial activity against Litomosoides carinii, some of the compounds showed moderate microfilaricidal activity.

Abstract
9,11-Secoestradiol (9) and 11-hydroxy-9,11-secoestradiol (12) have been synthesized starting from 17-acetoxyestradiol 3-methyl ether (1) and found to possess significant antifertility activity in rats. 3-Methoxy-9,11-seco-9-oxo-17beta-acetoxyestra-1,3,5(10)-trien-11-oic acid (2), prepared by CrO3 oxidation of 1, on hydrogenolysis gave methyl 17beta-hydroxy-3-methoxy-9,11-secoestra-1,3,5(10)-triene-11-carboxylate (3). The 17-O-THP derivative of 3 was treated with LiAlH4 to give 17beta-(O-tetrahydropyranyl)-3-methoxy-11-hydroxy-9,11-secoestra-1,3,5(10)-triene (5). The 11-O-mesylate of 5 on LiAlH4 reduction followed by mild acid treatment and demethylation under alkaline conditions gave 9. LiAlH4 reduction of 3 gave 9,11-seco-11-hydroxyestradiol 3-methyl ether (11) which on demethylation gave 9,11-seco-11-hydroxyestradiol (12).
