In the title compound, C12H17NO3, which was synthesized by Wagner-Meerwein rearrangement of the N-nitro-imine, the ring-junction C-C bond length is comparatively long [1.573 (2) Å] due to a steric repulsion between the methyl groups at these atoms, which also leads to an increase in the C-C-C angles along this C4 chain [118.10 (13) and 115.04 (15) °, respectively]. In the crystal, N-H⋯O-C and N...

In the title compound, C(15)H(12)ClNO(2), the two benzene rings adopt a syn configuration with respect to the ep-oxy ring; the dihedral angles between the ep-oxy ring and the two benzene rings are 59.71 (16) and 67.58 (15)°. There is a weak intra-molecular N-H⋯O bond, which may help to establish the conformation. In the crystal, the mol-ecules are linked into a chain parallel to the b axis thro...

In the title compound, C(24)H(39)NO(2)·H(2)O, the A and C rings of the pregnolene derivative sterol adopt chair conformations, with the B ring in a flattened chair conformation and the five-membered ring in an envelope conformation twisted about the C/D ring junction. The N-tert-butyl-carboxamide substituent is equatorial. The 3β-hydr-oxy H atom and one H atom of the water mol-ecule are disorde...

The insect repellents N,N-diethyl-3-methylbenzamide (Deet) and the racemate and 1S,2'S stereoisomer of 2-methylpiperidinyl-3-cyclohexene-1-carboxamide (AI3-37220) were tested against Anopheles albimanus Wiedemann and Aedes aegypti (L.) in laboratory human-volunteer assays. Estimated skin doses of Deet or racemic AI3-37220 required to reduce biting by 95% in Ae. aegypti were 2.3 and 3.5 x 10(-2)...

In the title compound, C(20)H(20)N(2)O, the dihedral angle between the quinoline ring system and the phenyl ring is 49.40 (5)°. In the crystal structure, zigzag layers of mol-ecules, in which the quinoline units are parallel to the (10) plane, are arranged perpendicular to the b axis. Inter-molecular N-H⋯O hydrogen bonds connect the mol-ecules into chains along [010], reinforcing the cohesion b...

Linomide (N-phenylmethyl-1,2-dihydro-4-hydroxyl-1-methyl-2-oxoquinoline-3-carboxa mide) has a reproducible in vivo antitumor effect against a series of both androgen responsive and independent Dunning R-3327 rat prostatic cancers. This antitumor effect of linomide is host mediated. One possible mechanism involving the host is that linomide has antiangiogenic activity. An indication that linomid...

In the title compound, [Ag(C(12)H(9)ClN(2)O)(2)]NO(3), two N atoms from two pyridine rings of two N-(4-chloro-phen-yl)pyridine-3-carboxamide ligands coordinate to the Ag(I) atom, forming a nearly linear geometry with an N-Ag-N angle of 173.41 (7)°. The crystal structure is stabilized by N-H⋯O, C-H⋯O and C-H⋯Cl hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 3.5469 (1...

Three independent mol-ecules comprise the asymmetric unit of the title compound, C10H19N5O2, (systematic name: 4-amino-N-tert-butyl-3-isopropyl-5-oxo-4,5-dihydro-1H-1,2,4-triazole-1-carboxamide) . In all three mol-ecules, the triazole ring and the carboxamide group are almost coplanar [within 4.0-5.9 (9)°], particularly because of the formation of an intra-molecular N-H⋯O hydrogen bond. On othe...
