B vitamins like B2, B6, B12, and Folate are essential for making and recycling glutathione
In terms of ubiquitination, the small molecule N6F11 specifically recruits the E3 ligase TRIM25, which catalyzes the polyubiquitination of lysine 48 (K48) on GPX4, leading to its proteasomal degradation

Documented mechanisms of action Preclinical studies (mostly Russian, to be reproduced in international protocols) report several mechanistic targets: BDNF increase (Brain-Derived Neurotrophic Factor) in the hippocampus and frontal cortex, measured by ELISA and Western blot 24-72 h post-administration Monoaminergic system modulation : cortical dopamine increase, serotonergic modulation Activation of the melanocortin pathway via MC4R receptors (residue shared with ACTH) Anti-oxidant and anti-apoptotic effect in cerebral ischaemia models (MCAO, middle cerebral artery occlusion) Experimental paradigms The most reported rodent models are the Morris water maze (spatial memory), novel object recognition (recognition memory), passive avoidance (aversive learning)
Our results further show that efficient conversion depends on a defined balance between free thiolate and nitrosylated cysteine species, consistent with a mechanism in which transient S-nitrosylation facilitates thioldisulfide exchange
