From the Vietnamese plant Macrosolen tricolor (Lecomte) Danser, one new diarylpropanoid, named macrotricolorin A () together with three diarylheptanoids including bisdemethoxycurcumin (), demethoxycurcumin () and curcumin (), were isolated. Their structures were elucidated by intensive analyses of their IR, UV, HR-ESI-MS and NMR (1 D & 2 D) spectra. It is the first time that diarylalkanoids have been reported from the genus Macrosolen. Compound exhibited anti-inflammatory activity against the nitric oxide (NO) production in lipopolysaccharide (LPS)-induced RAW264.7 with an IC50 value of 27.54 ± 1.75 μM. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Name: Bisdemethoxycurcumin).
Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Name: Bisdemethoxycurcumin
