D Gizachew et al.
Solid state nuclear magnetic resonance, 3(2), 67-78 (1994-04-01)
Solid-state 13C nuclear magnetic resonance (NMR) spectra of a number of inclusion compounds of 2,6-dimethyl-bicyclo[3.3.1]nonane-exo-2-exo-6-diol (host) with small organic small molecules (guests) have been studied. With 3,4-dichloro-1,2,5-thiadiazole and tetrachloroethylene as guests, line splittings of the host resonances were observed due

Amino acid derivatives of 1,2,5-thiadiazol-3-yl-piperazine related to (+)-WAY-100135 and WAY-100635 are potent 5-HT1A receptor agonists and antagonists, which have selective affinity for 5-HT1A receptors versus alpha1 and dopamine (D2, D3, and D4) receptors.
