Crystal structure of 17-(2'-(1'-oxa-4'-aza-heterocyclohexyl-1'-)ethylamino)- 17-demethoxygeldanamycin dihydrate, C34H54N4O11

1-Cyano­methyl-4-aza-1-azonia­bicyclo­[2.2.2]octane bromide dihydrate

In the crystal structure of the title compound, C(8)H(14)N(3) (+)·Br(-)·2H(2)O, inter-molecular O-H⋯O and O-H⋯Br hydrogen bonding occurs. The water mol-ecules are connected into chains extending in the a-axis direction. The bromide anions are connected to the water mol-ecules, forming 10-membered rings. The cations are connected to the anions via weak C-H⋯Br inter-actions. Two carbon atoms of t...

Crystal structure of 1-(1-methyl-1H-imidazol-2-yl)-4-phenyl-1H-1,2,3-triazole dihydrate.

The title compound, C12H11N5·2H2O, which crystallizes as a dihydrate, was obtained by Cu(I)-catalysed azide-alkyne cyclo-addition from 2-azido-1-methyl-imidazole and phenyl-ethyne. The dihedral angles between the central triazole ring (r.m.s. deviation = 0.004 Å) and the pendant imidazole (r.m.s. deviation = 0.006 Å) and phenyl rings are 12.3 (2) and 2.54 (19)°, respectively. In the crystal, th...

Crystal structure of di-μ2-chlorido-bis­[(1-aza-4-azoniabi­cyclo­[2.2.2]octane-κN 1)di­chlorido­dicadmium]

In the structure of the binuclear title compound, [Cd2(C6H13N2)2Cl6], two Cd(II) atoms are bridged by two Cl(-) ligands, defining a centrosymmetric Cd2Cl2 motif. Each metal cation is additionally coordinated by two Cl(-) ligands and the N atom of a protonated 1,4-di-aza-bicyclo-[2.2.2]octane (H-DABCO)(+) ligand, leading to an overall trigonal-bipyramidal coordination environment with one of the...

Six- and Seven-Membered 1-Oxa-4-Aza-2-Silacyclanes as Possible Correctors of Adaptational Mechanisms

The biological activity of eight 1-oxa-4-aza-2-silacyclanes with the OSiCH(2)N fragment including 6-membered 2-sila-5-morpholinones (1-3) and 4-acyl-2-silamorpholines (4-6)and previously unknown 7-membered derivatives of salicylic acid (7, 8) was studied. Compounds 1 and 3-6 show the certain antihypoxic action. Compounds 2 (40 mg/kg), 4 (20 mg/kg), 6 (40 mg/kg), 7 (20 mg/kg) and 8 (40 mg/kg) re...
