A short synthetic route to phosphonate prodrugs by olefin cross-metathesis, which uses either (acyloxymethyl) or (hexadecyloxypropyl) allylphosphonate building blocks is described. A study of eight ruthenium catalysts including the Ru-indenylidene catalyst, which bears the N-heterocyclic carbene 1,3-bis(2,6-diisopropylphenyl)-4,5-dihydroimidazol-2-ylidene, was undertaken. This method was applied to the synthesis of acyclonucleoside phosphonate prodrugs. This strategy is appealing for further uses in pharmaceutical and medicinal research.

The invention provides a benzodiazepine compound as well as a preparation method and a medicine effect thereof, and belongs to the field of chemical medicine. The benzodiazepine compound is a compound shown in formula I. Or a salt thereof, or a stereoisomer thereof, or a solvate thereof, or a eutectic thereof, or a composition thereof. The anesthetic effect of the compound of the invention is good, and the anesthetic effect of the compound is equivalent to that of Ramozolam, and even better than that of repirzolam, and particularly shows that the effective dosage is obviously reduced, and the duration and the recovery time are remarkably reduced. At the same time, in the rat tail vein anesthesia model, the compound of the present invention is remarkably improved in comparison with the quality of the Ramozolam wake-up. The compound has the advantages of high effectiveness, short duration, fast resuscitation and good tolerance, can be used for anesthesia induction, anesthesia maintenance and inter-day operation anesthesia, and has a good application prospect.

Recent post hoc analyses of several clinical trials with P2Y12 antagonists showed the need for new molecules being fully efficacious as antiplatelet agents and having a reduced propensity to cause major bleeding. We have previously reported the discovery of the 2-phenylpyrimidine-4-carboxamide analogs as P2Y12 antagonists with nanomolar potency in the disease-relevant platelet aggregation assay in human plasma. Herein we present the optimization steps that led to the discovery of clinical candidate ACT-246475 (30d). The key step was the replacement of the carboxylic acid functionality by a phosphonic acid group which delivered the most potent molecules of the program. In addition, low in vivo clearance in rat and dog was achieved for the first time. Since the bioavailability of 30d was low in rat and dog, we developed the bis((isopropoxycarbonyl)oxy)methyl ester prodrug (ACT-281959, 45). Compound 30d showed efficacy in the rat ferric chloride thrombosis model when administered intravenously as parent or orally as its prodrug 45. Moreover, 30d displays a wider therapeutic window as compared to clopidogrel in the rat surgical blood loss model.
