- Asymmetric Formal Synthesis of (+)-Catharanthine via Desymmetrization of Isoquinuclidine
-
Although (+)-catharanthine is an attractive alkaloid for both clinical research and organic synthetic chemistry, only a limited number of approaches for its catalytic asymmetric synthesis exist. Herein, we describe a novel strategy for synthesizing a chir

- Inhibition of noroviruses by piperazine derivatives
-
There is currently an unmet need for the development of small-molecule therapeutics for norovirus infection. The piperazine scaffold, a privileged structure embodied in many pharmacological agents, was used to synthesize an array of structurally-diverse derivatives which were screened for anti-norovius activity in a cell-based replicon system. The studies described herein demonstrate for the first time that functionalized piperazine derivatives possess anti-norovirus activity. Furthermore, these studies have led to the identification of two promising compounds (6a and 9l) that can be used as a launching pad for the optimization of potency, cytotoxicity, and drug-like characteristics.

- PYRROLIDINE DERIVATIVE OR SALT THEREOF
-
[PROBLEMS] To provide a compound which can be used for the treatment of a disease associated with a calcium-sensing receptor (CaSR), particularly hyperparathyroidism. [MEANS FOR SOLVING PROBLEMS] It is found that a novel pyrrolidine derivative having an aminomethyl group substituted by an arylaklyl group or the like or a salt thereof has an excellent CaSR agonistic modulation effect and also has an excellent selectivity in the inhibition of CYP2D6 which may cause a drug-drug interaction. Thus, the novel pyrrolidine derivative is useful as a therapeutic agent for a disease associated with CaSR (e.g., hyperparathyroidism, renal osteodystrophy and hypercalcemia).
