The title compound, C(30)H(50)O(5), was isolated from the bark of Aglaia smithii. There are two independent mol-ecules in the asymmetric unit that differ in the orientation of the isopropenyl group attached to the cyclo-hexane ring. The cyclo-hexane rings in both mol-ecules adopt chair conformations, whereas the cyclo-pentane and tetra-hydro-furan rings adopt envelope conformations. The indepen...

In the title compound, C12H14N2S, the cyclo-hexane ring adopts a chair conformation with the exocyclic C-C bond in an equatorial orientation. The mean plane through the cyclo-hexane ring (all atoms) is twisted from the thia-zolo-pyridine ring system (r.m.s. deviation = 0.013 Å) by 39.57 (6)°. In the crystal, mol-ecules form (100) sheets, although there are no specific directional inter-actions ...

This study evaluated the antimicrobial activity of Ficus exasperata and compared the efficacy of ethanol and hexane extracts on five microbial isolates. To ascertain the set objective, after extraction with ethanol and hexane, the disk and well diffusion agar methods were employed to investigate the antimicrobial activity of the extracts and its minimum inhibitory and bactericidal concentration...

Synthesis of the model compounds of carzinophilin carrying 2-methylidene-1-aza-bicyclo[3.1.0]hexane systems was achieved. Formation of malonylidenes or N-acyl-glycinylidenepyrrolidines was carried out by utilizing Eschenmoser’s sulfide contraction or Herdeis’s condensation between the 2-methylthio-D-pyrrolone derivatives and ethyl nitroacetate, respectively. The 1-azabicyclo-[3.1.0]hexane syste...

The title mol-ecule, C(19)H(18)N(2)O(2), is built up from three fused rings, viz. phenyl, pyrrole and cyclo-hexane, linked to a nitro-benzyl group. The C atom bearing the nitro-benzyl group is chiral and the compound is a racemate (R/S). The dihedral angle between the nitro-benzyl and indole rings is 57.49 (5)°. The cyclo-hexane ring adopts a slightly distorted chair conformation.

Mosquitoes are vectors of several human pathogens, and great attention has recently been placed on insecticides from plant-derived products, in search for mosquito control agents. This study, thus, investigated the potency of Boswellia dalzielii methanol leaf extract and its four fractions as mosquito ovicide, larvicide, and pupicide against Anopheles gambiae and Culex quinquefasciatus. The pla...

The present study analyzed, the influence of the treatment with juvenile hormone on the ultrastructure of Apis mellifera L. workers' venom glands. Newly emerged workers received topical application of 1 microl of juvenile hormone diluted in hexane, in the concentration of 2 microg/pl. Two controls were used; one control received no treatment (group C1) and other received topical application of ...

The methanolic extract along with some organic soluble fractions of the bark of Dillenia indica Linn. were tested against four Gram-positive and seven Gram-negative bacteria and against three pathogenic fungi. n-Hexane and dichloromethane fractions showed remarkable activities against all the tested bacteria but n-Hexane fraction showed highest activity against Shigella dysenteriae and its zone...

Solvent fractionation of high oleic-high stearic (HOHS) sunflower oil was studied to determine the best solvent to use (hexane or acetone) in terms of the operational parameters and properties of the final stearins. Acetone fractionation on two types of HOHS sunflower oils (N17 and N20) was carried out at temperatures from 5 to 10 °C using micelles with different oil/solvent ratios. Acetone was...

The title compound, C(6)H(15)N(2) (+)·NCS(-), was obtained unexpectedly from the reaction mixture of benzoyl chloride, ammonium thio-cyanate and cyclo-hexane-1,2-diamine. The cyclo-hexane ring adopts a chair conformation. In the crystal, N-H⋯S and N-H⋯N inter-actions involving the thio-cyanate anion and both the amine and the aminium N atoms link the mol-ecules, forming two-dimensional networks...
