Effect of lathyrane-type diterpenoids in neural stem cell physiology: Microbial transformations, molecular docking and dynamics studies.

Promoting endogenous neurogenesis for brain repair is emerging as a promising strategy to mitigate the functional impairments associated with various neurological disorders characterized by neuronal death. Diterpenes featuring tigliane, ingenane, jatrophane and lathyrane skeletons, frequently found in Euphorbia plant species, are known protein kinase C (PKC) activators and exhibit a wide variety of pharmacological properties, including the stimulation of neurogenesis. Microbial transformation of these diterpenes represents a green and sustainable methodology that offers a hitherto little explored approach to obtaining novel derivatives and exploring structure-activity relationships.

The NLRP3 inhibitor Dapansutrile improves the therapeutic action of lonafarnib on progeroid mice.

The role of the inflammasomes in aging and progeroid syndromes remain understudied. Recently, MCC950, a NLRP3 inhibitor, was used in Zmpste24 mice to ameliorate the phenotypes. However, the safety of MCC950 was questioned due to liver toxicity observed in humans.

A Biomimetic Approach to Premyrsinane-Type Diterpenoids: Exploring Microbial Transformation to Enhance Their Chemical Diversity.

Premyrsinane-type diterpenoids have been considered to originate from the cyclization of a suitable 5,6- or 6,17-epoxylathyrane precursor. Their biological activities have not been sufficiently explored to date, so the development of synthetic or microbial approaches for the preparation of new derivatives would be desirable. Epoxyboetirane A () is an 6,17-epoxylathyrane isolated from in a large enough amount to be used in semi-synthesis.
