Chemicals & Small Molecules

Gemcitabine triphosphate (dFdCTP), alongside its counterpart, the active diphosphate (dFdCDP), represents one of the two primary nucleoside metabolites of Gemcitabine within cellular structures. It serves as a benchmark in radiolabeled probe imaging investigations aimed at pinpointing tumors responsive to Gemcitabine. Furthermore, it is instrumental in assessing the compound's absorption and retention by cells [1] [2].

SB-435495 is an orally active, selective and potent Lp-PLA2 inhibitor (IC50 of 0.06 nM) for the study of autoimmune uveitis and atherosclerosis.

MM-401 (TFA), an MLL1 H3K4 methyltransferase inhibitor, effectively impedes MLL1 activity (IC 50 = 0.32 µM) by preventing MLL1-WDR5 interaction. It can induce cell cycle arrest, apoptosis, and differentiation, offering potential for MLL leukemia research [1].

Spectinomycin, a broad-spectrum antibiotic, targets and inhibits the growth of various gram-positive and gram-negative organisms by selectively binding to the bacterial ribosome, disrupting protein synthesis. Additionally, it serves as a noncompetitive inhibitor of td intron RNA [1] [2] [3] [4] [5].

ATP dimagnesium is an important substance for energy storage and metabolism in the body and is involved in the energy cycle and metabolism of the body.ATP dimagnesium can act as a coenzyme in cells and can be used as a signaling molecule.

CDP-Star is a luminescent substrate for 1,2-dioxetane and a substrate for alkaline phosphatase.CDP-Star can be used for in vivo imaging by detecting mRNA on Northern blot.

Ethidium monoazide bromide, a fluorescent dye that intercalates with DNA, selectively penetrates bacteria possessing compromised membranes. Upon photoactivation, it forms covalent bonds with DNA, enabling it to exclusively stain dead cells [1].

Liperfluo, a ferroptosis marker and fluorescent probe, efficaciously investigates lipid peroxidation's impact across numerous cellular pathophysiologies. It converts lipid hydroperoxides into lipid alcohols, facilitating the imaging of lipid hydroperoxides within living cells [1] [2] [3].

Catechol O-methyltransferase (COMT) is a key enzyme in the regulation of melatonin synthesis, which is involved in the regulation of plant growth and development, and can be inhibited by structurally specific heparin oligosaccharides.
