Compositions comprising extracts or isolated or purified compounds from plants of the genus
Corydalis
provide prevention and treatment of hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, hepatic steatosis, and metabolic syndrome.
Corydalis
compounds and their derivatives of natural and synthetic origins lower total cholesterol, LDL-cholesterol, and triglycerides and increase hepatic LDL receptor expression and activate AMP-activated protein kinase. Specific stereoisomers of
Corydalis
compounds with lipid lowering activity include 14R-(+)-corypalmine, 14R,13S-(+)-corydaline, 14R-(+)-tetrahydropalmatin, (+)-corlumidin, d-(+)-bicuculline, and (+)-egenine.

One-pot, one-substrate, triangular chemoenzymatic cascades featuring transaminase (TAm) and norcoclaurine synthase (NCS) enables the formation of (S)-benzylisoquinoline and (S)-tetrahydroprotoberberine alkaloids.
The total synthesis of berberine and selected analogues. And their evaluation as amyloid β (Aβ) aggregation inhibitors is described. The key step in the synthesis, the assembly of the berberine framework, was accomplished using an intermolecular Heck reaction. Berberine analog 17 incorporating a tertiary amine moiety showed good anti Aβ aggregation activity, water solubility, and almost no toxicity
The present invention relates to methods and compositions that affect the GTP-binding activity of members of the Rho family GTPases, preferably Rac GTPases (Rac1, Raclb, Rac2 and/or Rac3).
