Palladium(II)-Catalyzed Enantioselective Arylation of α‑Imino Esters
A protocol for Pd(II)-catalyzed asymmetric arylation
of <i>N</i>-aryl imino esters has been developed. The method
affords
a practical and direct access to chiral arylglycine derivatives in
good yields and with high enantioselectivities
Siteselective and Enantiocomplementary C(sp<sup>3</sup>)–H Oxyfunctionalization for Synthesis of α‑Hydroxy Acids
Oxyfunctionalization of abundant carboxylic acids represents
a
direct approach to synthesizing α-hydroxy acids, which are valuable
intermediates of various active pharmaceutical ingredients. Although
ideal, the transformation is yet to be accomplished. Herein, enantiocomplementary
C(sp3)–H oxyfunctionalization for
the synthesis of α-hydroxy acids was realized by a cooperative
strategy of substrate engineering, homologue screening and protein
engineering of α-ketoglutarate-dependent nonheme iron aryloxyalkanoate
dioxygenases. The reaction provided concise synthetic routes toward
three types of 67 α-hydroxy acids with high efficiency and selectivity
(yield up to 90% and ee up to >99%). The distinctive
complementary reactions add to a growing repertoire of biocatalytic
oxyfunctionalization reactions

Metabolic Susceptibility of 2‑Chlorothioxanthone and Its Toxic Effects on mRNA and Protein Expression and Activities of Human CYP1A2 and CYP3A4 Enzymes
Thioxanthones
(TXs) are photoinitiators widely used in UV curable
resins and food packaging, and their residues have been frequently
detected in human bodies. Our current understanding of the susceptibility
of residual TXs to metabolism and their effects on human health
is very limited. The in vitro metabolism of TXs and its toxic
effects on cytochrome P450 (CYP) (the key xenobiotic metabolizing
enzymes) were examined in this study. 2-Chlorothioxanthone (2-Cl-TX)
significantly inhibited the enzymatic activities of CYP1A2 and CYP3A4
with IC50 of 8.36 and 0.86 μM, respectively. The
exposure to 2-Cl-TX at 2.5 μM up-regulated the mRNA expression
of CYP1A2 and CYP3A4 in human hepatocellular carcinoma cells to 3.03-fold
and 2.02-fold, respectively. 2-Cl-TX at 2.5 μM caused 2.19-fold
and 1.98-fold overexpression of CYP1A2 and CYP3A4, respectively. In
vitro studies revealed that 2-Cl-TX was biotransformed into two metabolites
through the sulfoxidation of the sulfur atom, or via the hydroxylation
of aromatic carbon. Results from this study, including the metabolic
susceptibility of residual 2-Cl-TX, the proposed metabolites and the
significant toxic effect on the activities, mRNA, and protein expression
of CYP1A2 and CYP3A4, are vital to the human health and safety risk
assessment from this ubiquitous xenobiotic
