Synthesis, Reactivity, Functionalization, and ADMET Properties of Silicon-Containing Nitrogen Heterocycles

Silicon-containing compounds have been largely ignored in drug design and development, despite their potential to improve not only the potency but also the physicochemical and ADMET (absorption, distribution, metabolism, excretion, toxicity) properties of drug-like candidates because of the unique characteristics of silicon. This deficiency is in large part attributable to a lack of general methods for synthesizing diverse organosilicon structures. Accordingly, a new building block strategy has been developed that diverges from traditional approaches to incorporation of silicon into drug candidates. Flexible, multi-gram-scale syntheses of silicon-containing tetrahydroquinoline and tetrahydroisoquinoline building blocks are described, along with methods by which diversely functionalized silicon-containing nitrogen heterocycles can be rapidly built using common reactions optimized to accommodate the properties of silicon. Furthermore, to better clarify the liabilities and advantages of silicon incorporation, select compounds and their carbon analogues were challenged in ADMET-focused biological studies.

Conformationally constrained ortho- Anilino diaryl ureas: Discovery of 1-(2-(1′-Neopentylspiro[indoline-3,4′-piperidine]-1-yl)phenyl) -3-(4-(trifluoromethoxy)phenyl)urea, a potent, selective, and bioavailable P2Y1 antagonist

Preclinical antithrombotic efficacy and bleeding models have demonstrated that P2Y1 antagonists are efficacious as antiplatelet agents and may offer a safety advantage over P2Y12 antagonists in terms of reduced bleeding liabilities. In this article, we describe the structural modification of the tert-butyl phenoxy portion of lead compound 1 and the subsequent discovery of a novel series of conformationally constrained ortho-anilino diaryl ureas. In particular, spiropiperidine indoline-substituted diaryl ureas are described as potent, orally bioavailable small-molecule P2Y1 antagonists with improved activity in functional assays and improved oral bioavailability in rats. Homology modeling and rat PK/PD studies on benchmark compound 3l will also be presented. Compound 3l was our first P2Y1 antagonist to demonstrate a robust oral antithrombotic effect with mild bleeding liability in the rat thrombosis and hemostasis models.

Design and synthesis of a metabolically stable and potent antitussive agent, a novel δ opioid receptor antagonist, TRK-851

We have previously reported on antitussive effect of (5R,9R,13S,14S)-17-cyclopropylmethyl-6,7-didehydro-4,5-epoxy-5′,6′-dihydro-3-methoxy-4′H-pyrrolo[3,2,1-ij]quinolino[2′,1′:6,7]morphinan-14-ol(1b) methanesulfonate (TRK-850), a selective δ opioid receptor antagonist which markedly reduced the number of coughs in a rat cough model. We designed TRK-850 based on naltrindole (NTI), a typical δ opioid receptor antagonist, to improve its permeability through the blood-brain barrier by introducing hydrophobic moieties to NTI. The ED50 values of NTI and compound 1b by intraperitoneal injections were 104 μg/kg and 2.07 μg/kg, respectively. This increased antitussive potency probably resulted from the improved brain exposure of compound 1b. However, 1b was extremely unstable toward metabolism by cytochrome P450. In this study, we designed and synthesized compound 1b derivatives to improve the metabolic instability, which resulted in affording highly potent and metabolically stable oral antitussive agent (5R,9R,13S,14S)-17-cyclopropylmethyl-6,7-didehydro-4,5-epoxy-8′-fluoro-5′,6′-dihydro-4′H-pyrrolo[3,2,1-ij]quinolino[2′,1′:6,7]morphinan-3,14-diol (1c) methanesulfonate (TRK-851).

4,4-Dimethyl-1,2,3,4-tetrahydroquinoline-based PPARα/γ agonists. Part I: Synthesis and pharmacological evaluation

Type-2 diabetes (T2D) is a complex metabolic disease characterized by insulin resistance in the liver and peripheral tissues accompanied by a defect in pancreatic β-cell. Since their discovery three subtypes of Peroxisomes Proliferators Activated Receptors were identified namely PPARα, PPARγ and PPARβ/(δ). We were interested in designing novel PPARγ selective agonists and/or dual PPARα/γ agonists. Based on the typical topology of synthetic PPAR agonists, we focused our design approach on 4,4-dimethyl-1,2,3,4-tetrahydroquinoline as novel cyclic tail.
