- High-efficiency synthesis method of methyl 4-piperidineacetate
-
The invention discloses a high-efficiency synthesis method of methyl 4-piperidineacetate. The high-efficiency synthesis method comprises the following steps: firstly, preparing a colloid; secondly, taking titanium tetrachloride, di-n-octyl ether, cetylamine and carbon disulfide as raw materials to prepare reaction liquid; adding the reaction liquid into the colloid and dropwise adding ammonia water for precipitating to prepare a catalyst; taking 4-picolinic acid as a raw material and preparing 4-nipecotic acid under the reaction of the catalyst; taking the 4-nipecotic acid as the raw materialto prepare the methyl 4-piperidineacetate. The method has the advantages of simple operation, low preparation cost, high yield of a target product and easiness in separation.

- Synthesis, biological evaluation, X-ray molecular structure and molecular docking studies of RGD mimetics containing 6-amino-2,3-dihydroisoindolin-1-one fragment as ligands of integrin αiIbβ3
-
A series of novel RGD mimetics containing phthalimidine fragment was designed and synthesized. Their antiaggregative activity determined by Born's method was shown to be due to inhibition of fibrinogen binding to αIIbβ3. Molecular docking of RGD mimetics to αIIbβ3 receptor showed the key interactions in this complex, and also some correlations have been observed between values of biological activity and docking scores. The single crystal X-ray data were obtained for five mimetics.

- Synthesis, biological evaluation and SAR studies of benzimidazole derivatives as H1-antihistamine agents
-
A series of benzimidazole derivatives have been designed, synthesized and evaluated for H1 antihistamine activity. Six compounds have showed potent antihistamine H1 activity. The primary SAR analysis indicated that benzyl or benzylidinyl substituted on the exo-nitrogen atom and C2 of the benzimidazole were significant. Further experiments indicated that compound 17d displayed excellent activity to reduce mast cell degranulation, moderate anti-PAF activity and decreased potency on hERG compared to astermizole. Hence compound 17d could serve as anti-allergic agent for further development.

- Discovery of Potent, Selective, and Orally Active Carboxylic Acid Based Inhibitors of Matrix Metalloproteinase-13
-
The matrix metalloproteinase enzyme MMP-13 plays a key role in the degradation of type II collagen in cartilage and bone in osteoarthritis (OA). An effective MMP-13 inhibitor would therefore be a novel disease modifying therapy for the treatment of arthritis. Our efforts have resulted in the discovery of a series of carboxylic acid inhibitors of MMP-13 that do not significantly inhibit the related MMP-1 (collagenase-1) or tumor necrosis factor-α (TNF-α) converting enzyme (TACE). It has previously been suggested (but not proven) that inhibition of the latter two enzymes could lead to side effects. A promising carboxylic acid lead 9 was identified and a convergent synthesis developed. This paper describes the optimization of 9 and the identification of a compound 24f for further development. Compound 24f is a subnanomolar inhibitor of MMP-13 (IC50 value 0.5 nM and Ki of 0.19 nM) having no activity against MMP-1 or TACE (IC50 of >10000 nM). Furthermore, in a rat model of MMP-13-induced cartilage degradation, 24f significantly reduced proteoglycan release following oral dosing at 30 mg/kg (75% inhibition, p 0.05) and at 10 mg/kg (40% inhibition, p 0.05).

Inhibitors of platelet-fibrinogen binding offer an opportunity to interrupt the final, common pathway for platelet aggregation.Small molecule inhibitors of the platelet fibrinogen receptor GPIIb/IIIa were prepared and evaluated for their ability to prevent platelet aggregation.Compound 23m (L-700, 462/MK-383) inhibited in vitro platelet aggregation with an IC50 of 9 nM and demonstrated a selectivity of >24000-fold between platelet and human umbilical vein endothelial cell fibrinogen receptors.Dose-dependent inhibition of ex vivo platelet aggregation induced by ADP was achieved with iv infusions 0.1-10 μg/kg/min of 23m in anesthetized dogs, with 10 μg/kg/min completely inhibiting platelet aggregation during the entire 6 h infusion protocol.Platelet aggregatability returned rapidly after the termination of the 23m infusions.These features suggest that 23m may be useful in the treatment of arterial occlusive disorders.
