Description
Neotuberostemonine (NTS) is one of the main antitussive alkaloids in the root of Stemona tuberosa Lour, it has a significant protective effect on bleomycin (BLM)-induced pulmonary fibrosis through suppressing the recruitment and M2 polarization of macrophages. Neotuberostemonine demonstrates antitussive properties in guinea pigs.
Biological Functions
Neotuberostemonine is an alkaloid originally isolated from S. tuberosa that has diverse biological activities. It inhibits LPS-induced increases in inducible nitric oxide synthase (iNOS) protein levels and NO production in RAW 264.7 cells when used at a concentration of 100 μM. Neotuberostemonine (50 μM) inhibits RANKL-induced osteoclast differentiation of RAW 264.7 cells. It reduces the citric acid-induced cough reflex in conscious guinea pigs when administered at a dose of 133 μmol/kg. Neotuberostemonine (40 mg/kg) inhibits pulmonary collagen deposition and fibrosis, as well as bronchoalveolar lavage fluid (BALF) monocyte and lymphocyte infiltration in a mouse model of bleomycin-induced pulmonary fibrosis.
Biological Activity
Neotuberostemonine, one of the main antitussive alkaloids in the root of Stemona tuberosa Lour, attenuates bleomycin-induced pulmonary fibrosis by suppressing the recruitment and activation of macrophages.
Check Digit Verification of cas no
The CAS Registry Mumber 143120-46-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,1,2 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 143120-46:
(8*1)+(7*4)+(6*3)+(5*1)+(4*2)+(3*0)+(2*4)+(1*6)=81
81 % 10 = 1
So 143120-46-1 is a valid CAS Registry Number.
