Fmoc-Aeg(N3)-OH is a click chemistry reagent containing an Azide. Alkylating the Nitrogen of an amide bond results in peptoid structures, which leads to conformational restrains, like N-methylation and allows backbone derivatisation. Altering cytotoxicity, bacterial cell selectivity and receptor pharmacology through formation of peptoid derivatives have been published for Cilengitide, Piscidin 1, and MC3, MC4 and MC5 receptor agonist. This building block enables design of macrocycles through intermolecular crosslinking or backbone stabilization through intermolecular ring-closure. This compound is a potential building block for the construction of (customized) peptide nucleic acids (PNAs) and for peptoid synthesis . Fmoc-Aeg(N3)-OH is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.

BMVC4 is a G-quadruplex (G4) stabilizer of the human telomeric sequence d[AG3(T2AG3)3]. Screening by circular dichroism (CD) spectroscopy revealed that BMVC4 is more suitable as the core molecule of G4 stabilizers than BMVC. The results showed that BMVC4-12C and BMVC4-8C3O are better candidates for G4 stabilizers and are worthy of further study. A simple and rapid screening method based on Cu2+-induced G4 unfolding can be used to find better G4 stabilizers for potential anticancer applications. CD results showed that the trivalent cations of 9-substituted BMVC derivatives are more suitable as G4 stabilizers than the divalent cations of BMVC. In addition, by monitoring the disappearance of the 291 nm CD band of human telomeres after Cu2+ addition, it was found that the core molecule of G4 stabilizer BMVC4 has better stability.

Fluorescent Dye

Research Areas:  

Cancer

C-TPA is a fluorescent probe used for hypochlorite detection and bioimaging of lipid droplet polarity in cancer cells. For hypochlorite detection, when its derivative C-TPA-S is exposed to hypochlorite, an oxidative desulfurization reaction converts the thiocarbonyl group of C-TPA-S to the carbonyl group of C-TPA, thus restoring bright fluorescence from the almost non-fluorescent C-TPA-S. For bioimaging of lipid droplet polarity, the intramolecular charge transfer process between its Triphenylamine (HY-W011998) donor group and Coumarin (HY-N0709) acceptor group endows C-TPA with solvatochromism-it exhibits stronger fluorescence in less polar environments (such as lipid droplets in cancer cells) and weaker fluorescence in more polar environments (such as lipid droplets in normal cells), enabling the differentiation of cancer cells and cancer tissues from normal cells and normal tissues. The excitation wavelength of C-TPA is 405 nm, and the emission wavelengths used for cell and tissue imaging cover 425-475 nm and 500-550 nm; in solvents, its emission peak shifts from 494 nm in non-polar toluene to 528 nm in polar water .
