Intermolecular Carbon–Carbon Naphthalene Coupling Involves a Radical Mechanism Driven by Cytochrome P450 in Alternaria alternata

open access: yesAngewandte Chemie, EarlyView.
1,8‐DHN is an important intermediate to form complex aromatic ring systems. Phenol‐coupling reactions are important for the dimerization of two molecules. Here, we show that a fungal cytochrome P450 enzyme catalyzes specific C─C bonds. ABSTRACT Dihydroxynaphthalene (DHN) derivatives are precursors of biologically important molecules, including melanin ...

Engineered Transformer Base Editor with Enhanced Editing Efficiency

open access: yesAdvanced Science, EarlyView.
A highly efficient transformer base editor system achieves robust genomic editing in a humanized mouse model. This work establishes a versatile and translatable platform, opening new avenues for precision gene therapy. ABSTRACT Canonical cytosine base editors (CBEs) achieve precise C‐to‐T conversions without inducing DNA double‐strand breaks (DSBs ...

Antimicrobial peptides and complement in neonatal hypoxia-ischemia induced brain damage [PDF]

open access: yes, 2015
Hypoxic-ischemic encephalopathy (HIE) is a clinical condition in the neonate, resulting from oxygen deprivation around the time of birth. HIE affects 1-5/1000 live births worldwide and is associated with the development of neurological deficits ...

Oral Vaccination with Attenuated Salmonella typhimurium-Delivered TsPmy DNA Vaccine Elicits Protective Immunity against Trichinella spiralis in BALB/c Mice. [PDF]

open access: yesPLoS Neglected Tropical Diseases, 2016
BACKGROUND:Our previous studies showed that Trichinella spiralis paramyosin (TsPmy) is an immunomodulatory protein that inhibits complement C1q and C8/C9 to evade host complement attack.

Raman Analysis of RNA Nucleotide Strands From SARS‐CoV‐2 Variants and Subvariants: A Step Forward in the Definition of “Raman Genome”

open access: yesAdvanced Science, EarlyView.
Main Raman signals in RNA, related to helical backbone, ribofuranose ring, and nitrogenous bases, are affected by secondary structures that cause hyperchromic effects and significantly alter the Raman intensity. ABSTRACT Raman spectra of RNA nucleotide strands extracted from 20 SARS‐CoV‐2 strains, including the original Japanese isolate, Alpha, Beta ...

The homology of complement factor C8 gamma chain and alpha-1-microglobulin

open access: yesBiochemical and Biophysical Research Communications, 1987
The sequence of the complement factor C8 gamma chain shares a remarkable degree of similarity with that of alpha-1-microglobulin, a member of the alpha-2u-globulin superfamily. This superfamily comprises a diverse group of distantly related animal proteins possessing characteristic structural features and similar functions.

A Versatile DNA‐Encoded Library Platform for the Discovery of Highly Cooperative Chemical Inducers of Proximity

open access: yesAdvanced Science, EarlyView.
We present a versatile DNA‐encoded library (DEL) platform designed for rapid library synthesis and subsequent screening for chemical inducers of proximity (CIPs) across various presenter proteins of choice. Applying this approach, we discovered a novel molecular glue‐like compound mediating CRBN‐BRD9 ternary complex formation with remarkable ...
