Synthesis of Indenones via Persulfate Promoted Radical Alkylation/Cyclization of Biaryl Ynones with 1,4-Dihydropyridines

open access: yesMolecules
The oxidative radical cascade cyclization of alkynes has emerged as a versatile strategy for the efficient construction of diverse structural units and complex molecules in organic chemistry.

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

open access: yesMolecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Efficient biosynthesis of heterodimeric C3-aryl pyrroloindoline alkaloids

open access: yesNature Communications, 2018
The hexahydropyrrolo[2, 3-b]indole (HPI) framework is found in many natural products. Here, the authors discover a P450 enzyme and develop a whole-cell biocatalysis system that produces the HPI naseseazine C (NAS-C) and 30 NAS-C analogs, several of which

In Vitro CRISPR/Cas9 System for Efficient Targeted DNA Editing

open access: yesmBio, 2015
The clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated protein 9 (Cas9) system, an RNA-guided nuclease for specific genome editing in vivo, has been adopted in a wide variety of organisms.

Mutation of the inducible ARABIDOPSIS THALIANA CYTOCHROME P450 REDUCTASE2 alters lignin composition and improves saccharification [PDF]

open access: yes, 2014
ARABIDOPSIS THALIANA CYTOCHROME P450 REDUCTASE1 (ATR1) and ATR2 provide electrons from NADPH to a large number of CYTOCHROME P450 (CYP450) enzymes in Arabidopsis (Arabidopsis thaliana).

Phenylpropanoid Biosynthesis [PDF]

open access: yesMolecular Plant, 2010
The general phenylpropanoid metabolism generates an enormous array of secondary metabolites based on the few intermediates of the shikimate pathway as the core unit. The resulting hydroxycinnamic acids and esters are amplified in several cascades by a combination of reductases, oxygenases, and transferases to result in an organ and developmentally ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

open access: yesMolecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Efficient editing DNA regions with high sequence identity in actinomycetal genomes by a CRISPR-Cas9 system

open access: yesSynthetic and Systems Biotechnology, 2019
Actinobacteria able to produce varieties of bioactive natural products have been long appreciated by the field of drug discovery and development. Recently, a few of CRISPR/Cas9 systems bearing different types of replicons (pSG5 and pIJ101) were developed

Mutations in the _SC4MOL_ gene encoding a novel methyl sterol oxidase cause autosomal recessive psoriasisiform dermatitis, microcephaly and developmental delay [PDF]

open access: yes, 2008
Disorders of cholesterol biosynthesis have clinical manifestations involving skeleton, eyes, neurologic development, and skin. We describe a patient with congenital cataracts, developmental delay, microcephaly, and low serum cholesterol who developed ...
