Four cases of toxic polyneuropathy due to glue-sniffing were reported. Neurological examination revealed motor predominant mixed type polyneuropathy. The cause of polyneuropathies in these cases was considered to be due to the inhalation of the vaporized elements of the adhesive agent, which contain mainly n-hexane and toluene. N-hexane is considered to be chiefly responsible for the polyneurop...

A twin inhibition is observed for the esterification reaction between ethanol and isovaleric acid using immobilized lipase from Rhizomucor miehei in hexane and in mixed solvent system. The observed bi-substrate inhibition pattern follows a Ping-Pong Bi-Bi mechanism with dead-end inhibition of enzyme by both the substrates. An increase in Km value for alcohol in mixed solvent (0.645 M) than in h...

In the title compound, C(25)H(36)N(2)O(2)S, the cyclo-hexane and morpholine rings adopt chair conformations. The cyclo-hexene and cyclo-hexane rings form a trans ring junction with the two methyl groups in axial positions. The N-H and C=O bonds in the urea group are anti to each other. The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds.

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 ...
