Attempted Synthesis of Vinca Alkaloids Condensed with Three-Membered Rings
Our successful work for the synthesis of cyclopropanated vinblastine and its derivatives by the Simmons–Smith reaction was followed to build up further three-membered rings into the 14,15-position of the vindoline part of the dimer alkaloid ...

Chapter 3 Noniridoid Bisindole Alkaloids
This chapter discusses that indole is a reactive nucleus prone to dimerization when it is isolated or a part of tryptamine or tryptophan, which themselves are reactive toward many functionalities. For these reasons, bisindoles, the majority of which are of iridoid origin, are frequently isolated in nature. Besides these “dimers,” there exists a growing

The Raputindoles: Novel Cyclopentyl Bisindole Alkaloids from Raputia simulans
A novel class of bisindole alkaloids is established by the isolation and structural determination of raputindoles A-D (1-4) from the Amazonian plant Raputia simulans Kallunki (Rutaceae). Complete spectroscopic characterization was accomplished by means of NMR spectroscopy and APCI (+) HRMS.

Type 2 diabetes mellitus (T2DM) is a state where the body’s glucose metabolism is compromised. AMP‐activated protein kinase, or AMPK, has an important part to play in glucose metabolism, and the liver kinase B1 (LKB1) protein functions as a major upstream kinase for AMPK activation, thereby making it appealing therapeutic targets for treating and ...
