Mutagenicity of electrophilic N-acyloxy-N-alkoxyamides

open access: yes, 2001
N-acyloxy-N-alkoxybenzamides are mutagenic in TA100 without the need for metabolic activation with S9. Electronic effects of substituents on both the benzamide ring in N-acetoxy-N-butoxybenzamides or the benzyloxy ring in N-acetoxy-N-benzyloxybenzamides ...

Engineered B7‐H3 Binding in Modular Gp2 Miniproteins

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT B7‐H3, an important immune checkpoint modulator of T‐cell function, is a tumor vasculature biomarker and is overexpressed in a variety of cancers. Its expression is associated with tumor growth, metastasis, and poor clinical prognosis, which makes B7‐H3 an appealing target for diagnostics and therapeutics.

Valorization of Yacon (Smallanthus sonchifolius) peel for peroxidase production and its immobilization on alginate beads for 2,4‐dichlorophenol bioconversion

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Sodium alginate was modified with EDC/NHS for the immobilization of Yacon peel peroxidase, resulting in a novel biocatalyst for the oxidation of 2,4‐dichlorophenol. Abstract Yacon (Smallanthus sonchifolius) roots are emerging as an alternative source of peroxidase. This study aimed to extract, immobilize, and characterize the peroxidase from Yacon peel,
