pyridoxal phosphate

Pyridoxal phosphate (Vitamin B6 phosphate) is the active form of vitamin B6 and a coenzyme for many pyridoxal phosphate (PLP)-dependent enzymes. PLP is involved in numerous enzymatic transamination, decarboxylation and deamination reactions; it is necessary for the synthesis of amino acids and amino acid metabolites, and for the synthesis and/or catabolism of certain neurotransmitters, including the conversion of glutamate into gamma-aminobutyric acid (GABA) and levodopa into dopamine. PLP can be used as a dietary supplement in cases of vitamin B6 deficiency. Reduced levels of PLP in the brain can cause neurological dysfunction.

4-Deoxypyridoxine (4-DPD) is a vitamin B6 antimetabolite with diverse biological activities. It inhibits transport of pyridoxine , pyridoxal, and pyridoxamine in and reduces growth of S. carlsbergensis cells. 4-DPD inhibits sphingosine-1-phosphate (S1P) lyase and reduces cyclic stretch-induced apoptosis in alveolar epithelial MLE-12 cells. 4-DPD (5 mg, i.p.) reduces lysyl oxidase activity by 26% and reduces collagen and elastin crosslinking, resulting in limb abnormalities in chick embryos. It decreases latency to first seizure in mice (ED50 = 1 mmol/kg) and increases the occurrence and duration of myoclonic responses in baboons with photosensitive epilepsy. 4-DPD reduces TNF-α and IL-6 production in mice infected with T. spiralis.

KSK-104 exhibits potent antibacterial activity against Mycobacterium tuberculosis, with a minimum inhibitory concentration (MIC) of 0.78 μM. Its mechanism of action primarily involves the synthesis and salvage pathway of pyridoxal 5'-phosphate (PLP), as well as PLP-dependent enzymes and the oxidative stress network. KSK-104 is a promising candidate for developing novel anti-tuberculosis drugs targeted at drug-resistant strains of Mycobacterium tuberculosis.
