“…We have studied in here the neurogenic effect of a small molecule, the diterpene with lathyrane skeleton EOF2. Unlike other lathyranes, EOF2 does not promote proliferation of NPC 22 . However, we have demonstrated that it specifically facilitates novel PKC-mediated NRG1 release, without affecting TGFα release.…”

“…The lathyrane EOF2 (CAS number 2230806-06-9) was previously described by our group as a diterpene with no effect on NPC proliferation 22 . Since other diterpenes induced proliferation of NPC 24 via classical PKC activation 23 , we analyzed its capacity to activate PKC and to facilitate the generation of neurospheres.…”

“…S1 D), it exerted no change in the size of the neurospheres and a reduction in the number of neurospheres generated. Given its capacity to activate PKC without inducing proliferation, it was possible that EOF2 specifically activated novel PKC without affecting the classical isozymes-reported as responsible of the proliferative effect 22 .…”

“…Previous reports have demonstrated the role of individual PKC isozymes as mediators of different steps in the neurogenic process 27,28 , some of them highlighting the role of non-tumor promoting diterpenes as PKC activators that promote neurogenesis in neurogenic niches 22,29 . However, neurogenic signaling molecules behave differently depending on the niche.…”

“…We searched for a compound able to deliver neuregulins to the injured brain tissue. We chose to study the effect of EOF2 because of its lack of effect on stimulating NPC proliferation in a classical PKC dependent manner 22 and its similarity to other classical PKC activating compounds (supplementary fig. 8).…”

Neural stem cells are activated within neurogenic niches in response to brain injuries. This results in the production of neuroblasts, which unsuccessfully attempt to migrate toward the damaged tissue. Injuries constitute a gliogenic/nonneurogenic niche generated by the presence of anti-neurogenic signals, which impair neuronal differentiation and migration. Kinases of the protein kinase C (PKC) family mediate the release of growth factors that participate in different steps of the neurogenic process, particularly, novel PKC isozymes facilitate the release of the neurogenic growth factor neuregulin. We have demonstrated herein that a plant derived diterpene, (EOF2; CAS number 2230806-06-9), with the capacity to activate PKC facilitates the release of neuregulin 1, and promotes neuroblasts differentiation and survival in cultures of subventricular zone (SVZ) isolated cells in a novel PKC dependent manner. Local infusion of this compound in mechanical cortical injuries induces neuroblast enrichment within the perilesional area, and noninvasive intranasal administration of EOF2 promotes migration of neuroblasts from the SVZ towards the injury, allowing their survival and differentiation into mature neurons, being some of them cholinergic and GABAergic. Our results elucidate the mechanism of EOF2 promoting neurogenesis in injuries and highlight the role of novel PKC isozymes as targets in brain injury regeneration.

ELAC (3,12‐di‐O‐acetyl‐8‐O‐tigloilingol), a plant‐derived lathyrane diterpene, induces subventricular zone neural progenitor cell proliferation through PKCβ activation

Abstract: We propose lathyranes like ELAC as new drug candidates to modulate adult neurogenesis through PKC activation. Functional and structural comparisons between ELAC and phorboids are included.
