β-Amyrin biosynthesis: the critical role of steric volume at C-19 of 2,3-oxidosqualene for its correct folding to generate the pentacyclic scaffold.
Org. Lett. 16(13) , 3548-51, (2014) The effect of the steric volume at C-19 of (3S)-2,3-oxidosqualene 1 on the polycyclization reaction by β-amyrin synthase was examined. The substrate analogs, in which the methyl group at C-19 of 1 was substituted by an ethyl group and hydrogen atom, were conv... |

Inhibitor selectivity between aldo–keto reductase superfamily members AKR1B10 and AKR1B1: Role of Trp112 (Trp111)
FEBS Lett. 587(22) , 3681-6, (2013) • Crystal structures of AKR1B10 holoenzyme. • Trp112 side-chain flipping in AKR1B10 explains non-selectivity of AKR1B1 inhibitors. • Native Trp112 side-chain orientation is critical for selective AKR1B10 inhibitors. |

The supplementation of Korean mistletoe water extracts reduces hot flushes, dyslipidemia, hepatic steatosis, and muscle loss in ovariectomized rats.
Exp. Biol. Med. (Maywood.) 240(4) , 477-87, (2015) Since Korean mistletoe (Viscum album) has been used for alleviating metabolic diseases, it may also prevent the impairment of energy, glucose, lipid, and bone metabolisms in an estrogen-deficient animal model. We determined that long-term consumption of Korea... |
