The treatment of schizophrenia, one of the most debilitating mental illnesses, began by the serendipitous discovery of chlorpromazine. Since then, researchers have endeavored to find the cause of the illness but it remains unresolved. As a result, literature on the etiology of schizophrenia is littered with hypotheses and theories that are constantly(More)
We report the development of homology models of dopamine (D(2), D(3), and D(4)), serotonin (5-HT(1B), 5-HT(2A), 5-HT(2B), and 5-HT(2C)), histamine (H(1)), and muscarinic (M(1)) receptors, based on the high-resolution structure of the beta(2)-adrenergic receptor. The homology models were built and refined using Prime. We have addressed the required modeling(More)
While the general features of HIV-1 integrase function are understood, there is still uncertainty about the composition of the integration complex and how integrase interacts with viral and host DNA. We propose an improved model of the integration complex based on current experimental evidence including a comparison with the homologous Tn5 transposase(More)
The M4 mAChR is implicated in several CNS disorders and possesses an allosteric binding site for which ligands modulating the affinity and/or efficacy of ACh may be exploited for selective receptor targeting. We report the synthesis of a focused library of putative M4 PAMs derived from VU10004. These compounds investigate the pharmacological effects of(More)
To date all typical and atypical antipsychotics target the dopamine D(2) receptor. Clozapine represents the best-characterized atypical antipsychotic, although it displays only moderate (submicromolar) affinity for the dopamine D(2) receptor. Herein, we present the design, synthesis, and pharmacological evaluation of three series of homobivalent ligands of(More)
Clozapine is an effective atypical antipsychotic agent, with serious side effects. JL13 [5-(4-methylpiperazin-1-yl)-8-chloropyrido[2,3-b][1,5]benzoxazepine] is a potential new atypical antipsychotic, structurally modified from clozapine to resist oxidation so as to reduce haematological and cardiological side effects. To assess the potential clinical(More)
The title mol-ecule, C(20)H(31)NO(8), has pseudo-C2 symmetry about the C-N bond, with the bis-(tert-butoxy-carbon-yl)amino group twisted from the benzene ring plane by ca 60° and the bulky tert-butoxy-carbonyl (Boc) groups are orientated away from the substituted aniline group. As part of an anti-bacterial drug discovery programme furnishing analogues of(More)
