BACKGROUND/AIMS: P-glycoprotein (P-gp, i.e., MDR1) is associated with the phenotype of multidrug resistance (MDR) and causes chemotherapy failure in the management of cancers. Searching for effective MDR modulators and combining them with anticancer drugs is a promising strategy against MDR. Asiatic acid (AA), a natural triterpene isolated from the plant Centella asiatica, may have an antitumor activity. The present study assessed the reversing effect of AA on MDR and possible molecular mechanisms of AA action in MDR1-overexpressing cisplatin (DDP)-resistant lung cancer cells, A549/DDP...

Madecassoside (MS) and asiaticoside (AS) along with their aglycones, madecassic acid (MA) and asiatic acid (AA), are considered the major neuroactive triterpenoid constituents of Centella asiatica . In this study, we aimed to compare MS, AS, MA, and AA for their neurite outgrowth activities and mechanisms in Neuro-2a cells. Immunofluorescent cell staining showed MS and AS significantly increased the percentage of neurite-bearing cells (%NBC) and the neurite length with higher potency than MA and AA. The triterpenoid glycosides induced sustained extracellular signal-regulated protein kinases 1 and 2 (ERK1/2) phosphorylation, while their aglycones activated only transient signaling of ERK1/2...

BACKGROUND: Formation of scars after surgical incisions requires the proper appositions of elements contributing to the scarring process. The structural rebuilding of damaged tissues is essential in producing a linear scar. The excess of blood, foreign particles, exuberant sutures, necrotic tissue, possible infective agents, as well as the ongoing inflammatory process may produce a non-linear, sometimes painful keloidal scar. Centella asiatica (CA) extracts have been used topically since ancient times for preventing keloids (i...

Centella asiatica is widely used as a medicinal plant due to accumulation of the ursane-type triterpene saponins asiaticoside and madecassoside. The molecular structure of both compounds suggests that they are biosynthesized from α-amyrin via three hydroxylations, and respective cytochrome P450-dependent monooxygenases (P450 enzymes) oxidizing the C-28 and C-2α positions have been reported. However, a third enzyme hydroxylating C-23 remained elusive. We previously identified 40,064 unique sequences in the transcriptome of C...

Neurodegeneration is typically preceded by neuroinflammation generated by the nervous system to protect itself from tissue damage, however, excess neuroinflammation may inadvertently cause more harm to the surrounding tissues. Attenuating neuroinflammation with non‑steroidal anti‑inflammatory drugs can inhibit neurodegeneration. However, such treatments induce chronic side effects, including stomach ulcers. Madecassoside, a triterpene derived from Centella asiatica, is considered to be an alternative treatment of inflammation...
