5-Bromouridine is a brominated uridine nucleoside. The triphosphate form of 5-Bromouridine, 5BrdUTP, can substitute for TTP as a substrate for DNA polymerase and be incorporated into nascent DNA strands, rendering the resulting 5-bromouridine-labeled DNA photosensitive to 300 nm UV irradiation; upon UV irradiation, the 5BrdU signal decreases and dU is generated, accompanied by DNA strand breaks and cross-link formation. 5-Bromouridine is useful for studies on nucleoside structure and halogenated nucleoside-labeled nucleic acids .

Synonyms: Gramicidin soviet
Research Areas:  

Infection

Gramicidin S (Gramicidin soviet) is a cationic cyclic peptide antibiotic that selectively targets bacterial cell membranes and has anticancer activity. Gramicidin S also exerts antibacterial activity by destroying membrane integrity and interfering with membrane protein function. Gramicidin S inserts into the phospholipid bilayer through hydrophobic amino acid residues, specifically binds to negatively charged membrane lipids and disrupts membrane structure, thereby inhibiting cell division and cell wall synthesis, and ultimately causing bacterial death. Gramicidin S also inhibits ion channels, with IC50s of 41 μM, 24 μM, and 3 μM for Na +/K +-ATPase, tobacco leaf plasma membrane Mg 2+/K +-ATPase, and rat heart plasma membrane Ca 2+-ATPase, respectively .

Synonyms: 5-Methyldeoxycytidine (Standard)
5-Methyl-2'-deoxycytidine (5mdC) is an endogenous substrate of DNA methyltransferases (such as mammalian 5-C-MTase) and binds to DNA dependent on the formation of DNA stem-loop structures. 5-Methyl-2'-deoxycytidine guides de novo DNA methylation by acting as a methylation mark and activates the methylation of adjacent CpG sites in single-stranded DNA through cis action. 5-Methyl-2'-deoxycytidine regulates DNA methylation patterns by recruiting methyltransferases to specific chromatin regions, affecting chromatin condensation and gene expression. Its distribution in plant cells is related to cell proliferation and differentiation stages. The methylation level of 5-Methyl-2'-deoxycytidine is low in proliferating cells and high in differentiated cells .

Synonyms: (S)-Amlodipine; Levoamlodipine
Levamlodipine ((S)-Amlodipine; Levoamlodipin) is an orally active L-type calcium channel blocker and MMP-9 modulator with high permeability and retention properties. Levamlodipine significantly enhances plaque stability and improves lipid profiles by reducing blood pressure, decreasing systolic blood pressure variability, and inhibiting MMP-9 expression in atherosclerotic plaques. Levamlodipine not only alleviates cardiac and aortic hypertrophy and prevents renal atrophy, but also produces synergistic effects in blood pressure reduction and organ protection when combined with bisoprolol (HY-129029). Levamlodipine exerts no significant inhibitory effect on abdominal aortic intimal hyperplasia. When excessively accumulated in the epidermis, Levamlodipine may induce changes in keratin structure, impair the skin barrier and trigger inflammation; long-term use further exacerbates skin irritation caused by local administration. Levamlodipine can be used in research related to hypertension and atherosclerosis .
