New substituted 2-methylthiomethyl- and 2-methylsulphinylmethylenebenz- imidazoles with D 2 /5-HT(1A) activity
(Govi-Verlag Pharmazeutischer Verlag GmbH, 1998)
Several 2-methylthiomethylbenzimidazoles (3a-e) and the corresponding sulphinyl derivatives 4a-e were synthesized and evaluated measuring their in vitro binding affinity at the D 1 and D 2 dopamine (source: synaptosomal ...
Novel 5-[2-(N,N-di-n-propylamino)-ethyl]benzimidazole-derived high affinity dopaminergic ligands
(Govi-Verlag Pharmazeutischer Verlag GmbH, 1996)
Derivatives of a noncatechol dopamine (DA) bioisostere 5-[2-(N,N-di-n-propylamino)ethyl]-benzimidazole (15) were synthesized and checked for affinity towards D-1 and D-2 DA receptors (DAR). Ten compounds were obtained by ...
Cyclisation of alkoxy radicals. A semiempirical MNDO-PM3 study
(Royal Society of Chemistry, 1994)
The reactivity of the butoxy and 3-methylcyclohexyl radicals, as representatives of alkoxy radicals, was studied by MNDO-PM3 semiempirical MO method. In both cases it was found that the oxy radical underwent easily 1,5-H ...
Photochemically induced mercuric oxide - iodine oxidation of some unsaturated steroid compounds
(Pergamon, 1994)
Photochemically induced HgO/I2 oxidation of cholest-5-en-3α-ol (6) and cholest-5-en-3β-ol (7) afforded (Scheme 3) products arising from the corresponding alkoxy radicals (12, 13 and 14a,b) and from attack of the I2O ...
Essential oil of pinus heldreichii, needles
(Taylor and Francis, 1996)
Needle oils of Pinus heldreichii Christ, produced from five different growth stages at two different locations in Serbia were examined for yield and composition during 1994. Although only ten components were identified in ...
Covalent glycophospholipid binding to hemoglobin. A new post-translational modification occurring in erythrocytes exposed to insulin
(Serbian Chemical Society, 1996)
In this work a novel hitherto unrecognised hemoglobin (Hb) fraction, HbA1x, which we detected previously in hemolysates of erythrocytes exposed to high concentration of insulin under hypoglycemic conditions, both in vivo ...
Oxidation of carbon monoxide over Cu1-xCrxCo2O4 in the presence of sulfur oxides
(Springer, 1991)
Carbon monoxide oxidation activity and aging of Cu1-xCrxCo2O4 (0<x<1) spinels in the presence of sulfur oxides have been studied. The results obtained indicate that the sulfur tolerance is related to the presence of ...
Sesquiterpene lactones from Centaurea species: C. derventana and C. kosaninii

Degradative side reactions in the syntheses of exactly alternating silarylene-siloxane polymers
(Springer, 1992)
Four principal synthetic methods for preparation of exactly alternating silarylene-siloxane polymers: the chlorosilane, the acetoxysilane, the aminosilane and the ureidosilane polymerization reactions, were compared under ...
An improved approach to B-norsteroids: An one-pot preparation of 3β-acetoxy-5-oxo-5,6-seco-cholestan-6-oic and 3β-acetoxy-5,17-dioxo-5,6-seco-androstan-6-oic acids
(Serbian Chemical Society, 1998)
A simple one-put procedure for the synthesis of the 5,6-seco-steroidal acids 9a,b in described in this paper. It consists of the epoxidation of the ▲ 5 -steroids, i.e., cholesteryl acetate (8a) and 17-oxo-aandrost-5-en-3β-yl ...
