Study on Design, Synthesis and Herbicidal Activity of Novel 6-Indazolyl-2-picolinic Acids [PDF]

Molecules
Thirty-eight new 4-amino-3,5-dicholo-6-(1H-indazolyl)-2-picolinic acids and 4-amino-3,5-dicholo-6-(2H-indazolyl)-2-picolinic acids were designed by scaffold hopping and synthesized to discover potential herbicidal molecules.

Functional changes in the gut microbiota are associated with the intestinal phenotype in A20 haploinsufficiency. [PDF]

Pediatr Allergy Immunol
Abstract Background A20 haploinsufficiency (HA20) is an autoinflammatory disease driven by pathogenic variants in TNFAIP3, which plays a crucial role in regulating immune responses. The clinical manifestations of HA20 resemble those of inflammatory bowel disease (IBD), with prominent gastrointestinal (GI) involvement.
