Five undescribed benzopyran containing meroterpenoids, ganodercins Q-U, two undescribed benzofuran containing meroterpenoids, ganodercins V and W, and two known meroterpenoids were isolated from Ganoderma cochlear. Their structures were elucidated by using HRESIMS, NMR spectroscopy and computational methods. The results of biochemical studies using a palmitic acid (PA) induced insulin resistance (IR) model show that (-)-ganodercin Q, (+)-ganodercins R and W activate phospho-AKT (p-AKT) at 20 μM and improve glucose uptake in a concentration dependent manner. The results of renoprotection studies show that (+)-ganodercin S, cochlearol F, (+)- and (-)-ganodercins V reduce the expression of collagen I.

Three new meroterpenoids, cochlearins J-L (1-3) and three known meroterpenoids (4-6) were isolated from the fruiting bodies of Ganoderma cochlear. NMR (H and C NMR, H - H COSY, HSQC, HMBC and ROESY), and HRESIMS were employed for the structure elucidation of new compounds. The stereostructures of 1-3 were confirmed by calculated ECD and optical rotation methods.

Four novel epimeric meroterpenoids, ganadone A (1), 3',10'-di-epi-ganadone A (2), 10'-epi-ganadone A (3), and 3'-epi-ganadone A (4) as well as another pairs of epimers, ganadone B (5) and 10'-epi-ganadone B (6), with a same basic skeleton compound ganadone C (7), together with two lactonized meroterpenoids, ganadones D and E (8 and 9) were isolated from the fruiting bodies of Ganoderma cochlear. Compounds 1-7 were constructed with fascinating adjacent 6',7'-bifuran ring system. Fortunately, we have revised our previously reported structure cochlearol Q, which was proposed pyrano[6',7'-b]pyran ring system into 6',7'-bifuran motif.

(±)-Dimercochlearlactones A-J (-), ten pairs of novel meroterpenoid dimers and one known spirocochlealactone A (), were isolated from mushrooms. The structural elucidation of new compounds, including their absolute configurations, depends on spectroscopic analysis and electronic circular dichroism (ECD) calculations. Biological studies showed that (+)- and (-)-, (-)-, and (+)- and (-)- are cytotoxic toward human triple negative breast cancer (TNBC) cells (MDA-MB-231) with IC values of 28.
