OBJECTIVES The influence of 5-hydroxyadamantane-2-on was studied on the rats' brain blood flow and on morphological state of brain tissue under the condition of brain ischemia. The interaction of the substance with NMDA receptors was also studied. METHODS Study has been implemented using the methods of local blood flow registration by laser flowmeter, [(3)H]-MK-801binding, and morphological e...

The title adamantane derivative, C(12)H(21)NO·0.5H(2)O, was synthesized as part of an investigation into the biological activities of cage amino-alcohol compounds as potential anti-tuberculosis agents. The structure displays inter-molecular O-H⋯N, N-H⋯O, O-H⋯O hydrogen bonding and a layered packing structure with distinct hydro-philic and hydro-phobic regions. The water molecule lies on a twofo...

The nature and properties of radicals produced by the action of electron and ^-radiation on adamantane have been investigated. Radicals produced by irradiation at 77 °K are stable to around room temperature, while irradiation at the latter temperature yields well resolved spectra of species stable to about 130 °C. The significance of the latter, assigned as the 1-adamantyl radical, in the forma...

In the title compound, C(16)H(21)N(2)O(+)·Cl(-), the amide group makes a dihedral angle of 25.9 (1)° with respect to the pyridine ring. In the crystal, inter-molecular N-H⋯Cl bonds and weak C-H⋯Cl and C-H⋯O contacts link the cations and the anions into layers parallel to the ac plane. The layers are packed along [010] by hydro-phobic inter-actions between adamantane units.

The asymmetric unit of the title compound, C(18)H(23)NO(2), consists of two crystallographically independent mol-ecules bearing an adamantane cage consisting of three fused cyclo-hexane rings in almost ideal chair conformations, with C-C-C angles in the range 108.47 (16)-110.59 (15)°. Both aryl rings are essentially planar, the maximum deviation from the best plane being 0.0125 (19) Å. One conf...

A series of new trimethoprim [5-(3,4,5-trimethoxy-benzyl)-pyrimidine-2,4- diamine] analogues were prepared by condensation of adamantane-1-carbaldehyde with 3-methoxypropionitrile, followed by reaction of resulting mixture of 2-adamantan-1-ylmethyl-3-methoxy-acrylonitrile and 3-adamantan-1-yl-2-methoxymethyl-acrylonitrile with guanidine, acetamidine and thiourea, respectively. The activity of c...

A 192-member library of N,N'-disubstituted urea inhibitors was synthesized by a solid-phase method. The ureas were tested for their inhibitory activities against recombinant human soluble epoxide hydrolase. Simple carbocyclic or para/meta-substituted phenyl groups showed inhibition potencies that were equal to or greater than adamantane-based sEH inhibitors, while the presence of bulky or ioniz...

Photoreactive squaraines produce cytotoxic oxygen species under irradiation and have significant potential for photodynamic therapy. Herein we report that squaraines can be immobilized on a self-assembled nanocarrier composed of amphiphilic cyclodextrins to enhance their photochemical activity. To this end, a squaraine was equipped with two adamantane moieties that act as anchors for the cyclod...

In the title compound, [Co(C(12)H(15)O(4))(2)(H(2)O)(2)](n), adjacent Co(II) atoms ( symmetry) are bridged by 3-carboxy-adamantane-1-carboxyl-ate anions, forming a chain running along [001]. Inter-chain O-H⋯O hydrogen bonds link the chains into layers parallel to (100); the layers are further connected via inter-layer hydrogen bonds inter-actions, forming a three-dimensional framework.
