Discovery of a tetracyclic quinoxaline derivative as a potent and orally active multifunctional drug candidate for the treatment of neuropsychiatric and neurological disorders

We report the synthesis and structure-activity relationships of a class of tetracyclic butyrophenones that exhibit potent binding affinities to serotonin 5-HT2A and dopamine D2 receptors. This work has led to the discovery of 4-((6bR,10aS)-3-methyl-2,3,6b,9,10,10a-hexahydro-1H,7H- pyrido[3?,4?:4,5]pyrrolo[1,2,3-de]quinoxalin-8-yl) -1-(4-fluorophenyl)-butan-1-one 4-methylbenzenesulfonate (ITI-007), which is a potent 5-HT2A antagonist, postsynaptic D2 antagonist, and inhibitor of serotonin transporter. This multifunctional drug candidate is orally bioavailable and exhibits good antipsychotic efficacy in vivo. Currently, this investigational new drug is under clinical development for the treatment of neuropsychiatric and neurological disorders.

Direct hydroxyethylation of amines by carbohydrates: Via ruthenium catalysis

An efficient and halogen-free catalytic methodology for the synthesis of beta-amino alcohols from aromatic amines and biomass-derived carbohydrates is demonstrated for the first time. The activation of C5/C6 sugars by a ruthenium catalyst selectively generates the C2 alkylating reagent glycolaldehyde. The transformation involves metal-catalyzed hydrogen borrowing for the reduction of the imine intermediate. A series of arylamines bearing various substituents were successfully transformed into the desired products in good to excellent yields.

Studies on a novel, potent and orally effective cholecystokinin A antagonist, FK-480. Synthesis and structure-activity relationships of FK-480 and related compounds

We prepared various novel tricyclic 1,4-benzodiazepine derivatives as cholecystokinin (CCK) A antagonists, which were evaluated preliminarily for inhibition of 125I-CCK-8 binding to rat pancreatic membranes in vitro and inhibiting effect on CCK-8-induced inhibition of charcoal meal gastric emptying in mice. On the basis of structure-activity relationship (SAR) studies, as well as the stability and availability of the starting materials of those compounds, (S)-N-[1-(2-fluorophenyl)-3,4,6,7-tetrahydro-4-oxo-pyrrolo[3,2,1-jk][1 ,4]benzodiazepin-3-yl]1 H-indole-2-carboxamide (9f, FK-480) was selected as a candidate compound for further evaluation. The absolute configuration of the precursor of FK-480, (3S)-amino-1,4-benzodiazepine derivative ((S)-8a, R1 = F) was determined by an X-ray crystallographic study of its ureido derivative with (S)-alpha-methylbenzyl isocyanate. FK-480 is now undergoing clinical studies for the treatment of chronic pancreatitis.

A review on synthesis of benzothiazine analogues

Scientific advances mainly involves the development of new and highly reactive compounds. Nitrogen and sulphur containing benzothiazines forms highly active heterocyclic agents. Benzothiazines are prominent class of heterocyclic compound. Many studies have been done in the development of benzothiazine analogues. Microwave assisted synthesis, regioselective techniques and other methods are also used for benzothiazine synthesis. Various methods have been developed for the synthesis of benzothiazine derivatives. Benzothiazines exhibits numerous therapeutic activities like anti-HIV, calcium antagonistic, anti-serotinin, analgesic, anti-mycobacterial anti-microbial, anti-oxidant, anti-rheumatic, anti-inflammatory, anti-hypertensive ,calcium channel blocker, anti-malarial, potassium channel opener, cardiovascular, anthelmintic, neuroprotective, aldose reductase inhibitor, herbicidal, pesticidal etc. This has raised the necessity to explore novel benzothiazine derivatives which can significantly contribute to the development of therapeutically active agents. And the newer development of novel benzothiazines derivatives also involves the same characteristic features and also contribute various activities.

Development of high-affinity 5-HT3 receptor antagonists. Structure- affinity relationships of novel 1,7-annelated indole derivatives. 1

On the basis of the structures of ondansetron and GR 65,630, its ring- opened C-linked methylimidazole analogue, novel 1,7-annelated indole derivatives were synthesized as potential 5-HT3 antagonists. Receptor binding studies show that all compounds display a high affinity for the 5- HT3 receptors. In both series annelation results in compounds being 7 and 4 times more potent than the references ondansetron and GR 65,630, respectively. Similar to ondansetron, the 1,7-annelated indoles show little stereoselectivity. The (-)-isomers are only slightly more potent than the (+)-isomers. The receptor binding profile of l-10-[(2-methyl-1H-imidazol-1- yl)methyl]-5,6,8,9,10,11-hexahydro-4H-pyrido[3,2,1-jk]carbazol-11-one hydrochloride (24b) (INN cilansetron) shows that the compound displays, besides a high affinity for 5-HT3 receptors (K(i) = 0.19 nM), a weak affinity for sigma-receptors (K(i) = 340 nM), muscarine M1 receptors (K(i) = 910 nM), and 5-HT4 receptors (K(i) = 960 nM) and no affinity (K(i) ? 5000 nM) for all the other receptor types tested (n = 37). The new compounds fit the proposed necessary chemical template for binding: a heteroaromatic ring system, a coplanar carbonyl group, and a nitrogen center at well-defined distances. The enhanced potency of the annelated 1,7-indole derivatives indicates that the extra ring provides a favorable hydrophobic area for interaction with the 5-HT3 receptor site. In vivo cilansetron is more potent and induces less central side effects than ondansetron. At present cilansetron is in clinical trials.

Sodium Triethylborohydride-Catalyzed Controlled Reduction of Unactivated Amides to Secondary or Tertiary Amines

The first transition-metal-free catalytic protocol for controlled reduction of amide functions using cheap and bench-stable hydrosilanes as reducing agents has been established. By altering the hydrosilane and solvent, the new method enables the selective cleavage of unactivated C-O bonds in amides and allows the C-N bonds to selectively break via the deacylated cleavage. Overall, this novel process may offer a versatile alternative to current methodologies employing stoichiometric metal systems for the controlled reduction of carboxamides.
