We examined the involvement of multiple monoaminergic receptors in the induction of spontaneous tail-flicks (STFs) by the open channel blocker at N- methyl-D-aspartate (NMDA) receptors, dizocilpine, and the NMDA recognition site antagonist 3-(2-carboxypiperazin-4-yl)-propyl-1-phosphonic acid (CPP). At doses eliciting a maximal STF response, dizocilpine and CPP elevated levels of norepinephrine, but not dopamine or serotonin, in dialysates of nucleus accumbens, their known locus of action in eliciting STFs. Chemically diverse alpha2-adrenergic receptor (AR) antagonists atipamezole, L745,743, RX821,002, idazoxan, and desfluparoxan abolished induction of STFs by dizocilpine, whereas the preferential alpha1-AR antagonists prazosin, WB4101, and ARC239 were weakly active: relative potencies in blocking STFs correlated significantly with affinity at alpha2-ARs. The D1/D5 receptor antagonists SCH23390, SCH39166, and NNC756 potently abolished STFs, whereas the D2 antagonist L741,626, the D3 antagonists GR218,231 and S14297, and the D4 antagonists S18126 and L745,870 were inactive. D1 and alpha2-AR antagonists also blocked induction of STFs by CPP. Blockade of dizocilpine-induced STFs was specific inasmuch as idazoxan and SCH 23390 did not modify induction of ataxia by dizocilpine. Antagonists at multiple 5-hydroxytryptamine receptors failed to modify induction of STFs. Finally, dizocilpine-induced STFs were blocked by clozapine and 11 other antipsychotics, the potency of which correlated significantly with affinity at alpha2-ARs. In conclusion, STFs evoked by interruption or transmission at NMDA receptors are dependent on D1 receptors and alpha2-ARs for their expression. Antagonism of the alpha2-ARs is involved in their blockade by antipsychotics. This mode should facilitate exploration of interrelationships between glutamatergic and monoaminergic mechanisms involved in psychiatric and neurologic disorders.

Process development work to provide an efficient, robust, and cost-effective manufacturing route to avibactam, a beta-lactamase inhibitor is presented herewith. Aspects of this optimization work include the counterintuitive introduction of a protecting group to effect a difficult urea formation and the use of controlled feed hydrogenation conditions to facilitate an elegant one pot debenzylation and sulfation reaction. Overall, the commercial process delivers avibactam in much improved yield with significant reduction in the environmental footprint.

A series of 2- and 3-nitrothiophene-5-carboxamides bearing N-(omega-aminoalkyl) side chains has been prepared by treatment of the thiophenecarbonyl chloride with the appropriate (protected) omega-aminoalkylamine. Analogous N-(oxiranylmethyl)nitrothiophene-5-carboxamides have been synthesized by epoxidation of the corresponding N-allylamide. Compounds in both classes were evaluated in vitro both as radiosensitizers of hypoxic mammalian cells and as selective bioreductively activated cytotoxins. The most potent radiosensitizers were those agents with strong tertiary amine bases or oxiranes in the side chain. Studies in vivo showed that 2-methyl-N-[2-(dimethylamino)ethyl]-3-nitrothiophene-5-carboxamide caused slight radiosensitization of the KHT sarcoma in mice given 0.34 mmol kg-1. However, administration of this and related tertiary amines at higher doses was precluded by systemic toxicity.

Use of hazardous reagents is common in most of the reported synthesis of molecules of various interests. Hazardous reagents at a manufacturing scale pose a great challenge in terms of handling, operation and workups. These reagents are unsafe and found to have proven toxicity (in the majority of the cases). If not avoided, these reagents will defy the purpose of Green Chemistry and sustainability in organic synthesis. In this chapter, the synthesis of raloxifene, [6-Hydroxy-2-(4-hydroxyphenyl)-1-benzothiophen-3-yl]{4-[2-(piperidin-1-yl)eth-oxy] phenyl}methanone hydrochloride 1, an estrogen agonist/antagonist commonly considered as a selective estrogen receptor modulator (SERM), will be discussed considering the evolving trends of switching the usage of hazardous to less hazardous reagents. Raloxifene impedes the re-sorption of bone by reducing the biochemical markers of bone turnover in the premenopausal women thereby helping in the management of osteoporasis. Raloxifene hydrochloride also lowers the chances of developing a certain type of breast cancer (invasive breast cancer) in post-menopausal women.
