生物活性

製品説明 Thiamine or vitamin B1 is a water-soluble vitamin of the B complex, its phosphate derivatives are involved in many cellular processes.
in vitro Thiamine HCl (Vitamin B1) (50 mM), in addition to its nutritional value, induces systemic acquired resistance (SAR) in rice, tobacco, cucumber, and Arabidopsis. This compound-treated rice, Arabidopsis (Arabidopsis thaliana), and vegetable crop plants shows resistance to fungal, bacterial, and viral infections. It induces the transient expression of pathogenesis-related (PR) genes in rice and other plants. In addition, it potentiates stronger and more rapid PR gene expression and the up-regulation of protein kinase C activity. [1] At 10 μM, it prevents acetaldehyde-induced inhibition of myocyte shortening in adult rat ventricular myocytes, effectively blunts the acetaldehyde-induced depression in ±dL/dt, prevents acetaldehyde-induced shortening of time-to-peak shortening, and prevents acetaldehyde-induced elevation in both protein carbonyl formation and caspase-3 activation. [2] Its uptake is energy- and temperature-dependent, pH-sensitive, Na+-independent, saturable at both the nanomolar (apparent Km, 30 nM) and the micromolar (apparent Km, 1.72 mM) concentration ranges in ARPE-19 cells. Uptake of this compound is adaptively regulated by extracellular substrate level via transcriptionally mediated mechanisms that involve both hTHTR-1 and hTHTR-2 in ARPE-19 cells, it is also regulated by an intracellular Ca2+-calmodulin-mediated pathway. [3] Thiamine-responsive megaloblastic anemia (TRMA) fibroblasts are rescued from death with 10 nM-30 nM of it (in the range of normal plasma thiamine concentrations). Normal fibroblasts exhibits saturable, high-affinity thiamine uptake (Km 400 nM-550 nM; Vmax 11 pmol/min/1×106 cells), while TRMA fibroblasts lacks detectable high-affinity uptake. At 30 nM, the rate of uptake by TRMA fibroblasts is 10-fold less than that of wild-type, which explains the increased apoptosis of TRMA fibroblasts. [4]
in vivo Thiamine HCl (Vitamin B1) deficiency results in amyloid precursor protein immunoreactivity accumulated in swollen neurites within, or around lesions in rats, or in abnormal clusters in mice. [5]
