One Carbon at a Time: Unlocking Iterative Carboxylic Acid Homologation [PDF]

open access: yes
The development of a direct and iterative protocol for carboxylic acid homologation has constituted a long-standing challenge in synthesis. We recently disclosed an efficient and practical strategy for the homologation of unmodified carboxylic acids ...

Lipoxygenase and Its Relationship with Ethylene During Ripening of Genetically Modified Tomato (Solanum lycopersicum)

open access: yesFood Technology and Biotechnology, 2020
Research background. TomloxB is the main isoform of lipoxygenase associated with ripening and senescence of fruits. On the other hand, ethylene, a gaseous hormone, is essential for the regulation of ripening in climacteric fruits like tomatoes.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Visible Light–Induced Decarboxylative Radical Addition of Heteroaromatic Carboxylic Acids to Alkenes at Room Temperature in Two‐Molecule Photoredox System

open access: yesChemistryOpen
The photoinduced decarboxylative radical addition of aryl carboxylic acids, including heteroaromatic carboxylic acids, to electron‐deficient alkenes is achieved in a two‐molecule photoredox system using a combination of biphenyl (BP) and 9,10 ...

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Enantiopure Synthesis of All Four Stereoisomers of Carbapenam-3-carboxylic Acid Methyl Ester [PDF]

open access: yes, 2003
The retro-Dieckmann reaction has been used as a stereodivergent synthetic tool on N-Boc-7-azabicyclo[2.2.1]heptan-2-one-1-carboxylic acid methyl ester to obtain enantiopure trans- and cis-5-(carboxymethyl)pyrrolidine-2-carboxylic acid methyl esters ...
