从濒危植物大别山五针松(Pinus dabeshanensis)松针(干重仅30 g)的90%甲醇提取物中分离得到10个二萜类化合物,其中新化合物dabeshanensin L(1)的结构是通过运用1D/2D NMR等波谱手段进行确证的.体外活性测试结果表明化合物isopimara-7-en-18-oic acid(4)、trans-abienol(6)和lambertianic acid(8)对蛋白酪氨酸磷酸酶1B(PTP1B)有显著的抑制作用,其IC50值在14.6~37.7 μmol/L之间.

One new, dabeshanensin L (1), and nine known diterpenoids with diverse structures were isolated from the 90% MeOH extract of the needles (30 g dried mass-limited samples) of Pinus dabeshanensis, an endangered conifer listed in the China Plant Red Data Book (CPRDB). The new structure was established by detailed analysis of its spectroscopic data (IR, 1D/2D NMR, HRMS). Among the isolates, isopimara-7-en-18-oic acid (4), trans-abienol (6), and lambertianic acid (8) showed significant inhibitory activities against the human protein tyrosine phosphatase 1B (PTP1B) enzyme, a key target for the treatment of type-Ⅱ diabetes and obesity, with IC50 values ranging from 14.6 to 37.7 μmol/L.
