Light-enabled scalable synthesis of bicyclo[1.1.1]pentane halides and their functionalizations.

In 2012, bicyclo[1.1.1]pentanes were demonstrated to be bioisosteres of the benzene ring.

Synthesis of Multifunctional Spirocyclic Azetidines and Their Application in Drug Discovery.

The synthesis of multifunctional spirocycles was achieved from common cyclic carboxylic acids (cyclobutane carboxylate, cyclopentane carboxylate, l-proline, etc.). The whole sequence included only two chemical steps-synthesis of azetidinones, and reduction into azetidines.

Superoxide dismutase, catalase and glutathione peroxidase activities in the liver of young and old mice: linear regression and correlation.

Activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GP) were determined in the liver of 15 young (3-5 months) and 15 old (23-26 months) female CBA mice. Although, the activities of all three enzymes decreased in aging, only the SOD decline was statistically significant (P<0.01).

Pair-wise linear and 3D nonlinear relationships between the liver antioxidant enzyme activities and the rate of body oxygen consumption in mice.

Relationships between the rate of body oxygen consumption (VO2) and the liver key antioxidant enzyme activities were assessed in female CBA mice. The pair-wise linear regression and correlation demonstrated significant correlative links between VO2 and activity of catalase (CAT). Nonlinear 3D plotting revealed a complementary pattern of CAT and glutathione peroxidase (GP) relation.
