The Penicillium sp. KFS28 fungus was isolated from a bivalve mollusk, Meretrix Lusoria, from the Haikou Bay in China. The EtOAc extract of the fermentation broth was processed by the authors who isolated and identified four new paxilline-type indole-terpenoids. Compound 1 has the molecular formula C28H35NO6.

Goudou at al described the isolation of a novel metabolite, orbicularisine, from the tropical bivalve Codakia orbicularis living in seagrass beds, molecular formula C13H10N2O5S.

Feng et al investigated the chemical constituents of N. tabacum leaves by a dereplication procedure, which resulted in the isolation of a novel compound, nicotabin A, molecular formula C21H28O7.

Zhao and coworkers had been studying the secondary metabolites of Biscogniauxia sp. They isolated a diisoprenyl-cyclohexane-type meroterpenoid dimer with a new skeleton, Dimericbiscognienyne A (molecular formula C32H40O6).

Yaouba et al reported the isolation and phytochemical investigation of the constituents of Aspilia pluriseta Schweinf and Aspilia mossambicensis. They isolated, identified and comprehensively investigated compound 1, molecular formula C21H30O3.

El-Elimat et al reported five new and one known meroterpenoids, including the discovery of a novel ioxa[4.3.3]propellane metabolite neosetophomone A that incorporates a 3-methyl-2,3-dihydrofuran bridge into a 5,6 tricyclic 2-hydroxycyclopent-2-en-1-one/tetrahydropyran ring system, molecular formula C24H32O5.

Zhou et al isolated three novel diterpenoids with an unprecedented 2,3:5,6-di-seco-grayanane carbon skeleton. Rhodomollacetal A was obtained as colorless prisms, molecular formula C21H32O7.

As a part of an ongoing research for SNTs from Schisandra micrantha, a minor SNT featuring a complex tetracyclo[5.4.0.02,4.03,7]undecane-bridged system, termed lancolide E, was isolated by Shi et al, molecular formula C29H32O10.
