Twelve previously undescribed and four known lanostane triterpenoids were isolated from the fruiting bodies of Ganoderma calidophilum. The structures of undescribed compounds, ganodecalones H-S (1-12), were elucidated by extensive spectroscopic analysis as well as ECD and NMR calculations. Compound 4 showed significant inhibitory activity against human leukaemia cell line K562, gastric cancer cell line SGC-7901, and cervical cancer cell line HeLa with IC values of 13.10 ± 0.19, 17.26 ± 4.75, and 4.36 ± 0.58 μM, respectively. Compound 16 exhibited inhibitory potency against protein tyrosine phosphatase 1B (PTP1B) and α-glucosidase with IC values of 30.2 ± 0.13 μM and 120.6 ± 0.14 μM, respectively. The binding sites and interactions of 16 with PTP1B and α-glucosidase were revealed using molecular docking simulations.
从灵芝（Ganoderma calidophilum）的子实体中分离得到 12 个先前未描述的和 4 个已知的羊毛甾烷三萜。通过广泛的光谱分析以及 ECD 和 NMR 计算，阐明了未描述化合物 ganodecalones H-S（1-12）的结构。化合物 4 对人白血病细胞系 K562、胃癌细胞系 SGC-7901 和宫颈癌细胞系 HeLa 显示出显著的抑制活性，IC 值分别为 13.10±0.19、17.26±4.75 和 4.36±0.58 μM。化合物 16 对蛋白酪氨酸磷酸酶 1B（PTP1B）和 α-葡萄糖苷酶具有抑制活性，IC 值分别为 30.2±0.13 μM 和 120.6±0.14 μM。通过分子对接模拟揭示了 16 与 PTP1B 和 α-葡萄糖苷酶的结合位点和相互作用。
