Terpenoids from Azadirachta indica are potent inhibitors of Akt: Validation of the anticancer potentials in hepatocellular carcinoma in male Wistar rats

Abstract

Hepatocellular carcinoma (HCC) is the commonest primary malignancy with poor patient prognosis and a high mortality rate. In this study, phytochemicals characterized from Azadirachta indica were screened against the catalytic site of Akt, and the anticancer potentials of the extracted leads (terpenoids) were determined in hepatocellular carcinoma in male Wistar rats. The lead compounds are terpenoids; hence, the extraction of terpenoids from A. indica. Gas chromatography-mass spectrometry (GCMS) was employed for the characterization of the extract. Diethylnitrosamine (DEN)-induced hepatocellular carcinoma in male Wistar rats were treated with the terpenoids extract. The hit, lupeol demonstrates inhibition of Akt and is a potential drug candidate. The terpenoids extract downregulate Akt mRNA and demonstrated anti-Akt downstream signaling effects; anti-inflammatory, anti-angiogenesis, proapoptotic, and cell cycle arrest, it also demonstrated cellular regeneration, hepatoprotection, antioxidant potentials, and cellular repairs in hepatocellular carcinoma in male Wistar rats. Practical applications Hepatocellular Carcinoma (HCC) is the most common primary malignancy with poor patient prognosis and a high mortality rate. Akt, a serine/threonine kinase is at the crossroad of cell survival, the progression of the cell cycle, cell signaling, cell growth, cell division, and inactivation of pro-apoptotic factors. The inhibition of Akt is an effective therapeutic strategy against HCC. In this study, terpenoids from Azadirachta indica are potent inhibitors of Akt and hitherto demonstrate anticancer potentials. A. indica leaves are readily available globally and more also it is readily cultivated in African and Asia, continents with the highest prevalence of HCC. A. indica terpenoids extract demonstrate anti-HCC potentials and hence should be exploited in this regard.

Identification of Terpenoids FromAbrus precatoriusAgainst Parkinson’s Disease Proteins UsingIn SilicoApproach

“…The filtrate was concentrated under pressure with rotary evaporator. The method described by Akinloye et al 13 was employed for the fractionation of terpenoids. Briefly, a portion of the crude extract (56 g) was chromatographed on silica gel (with pore size 230-400 mesh) column with n-hexane/ethylacetate (85:15) as eluent.…”

“…Treatment of HER2 + breast cancer with chemotherapy and radiotherapy is associated with different complications and unpleasant side effects ( 6 ). Plant-derived phytochemicals are known to demonstrate excellent anti-neoplastic properties ( 7 , 8 ). These include the carotenoids; the dietary intake of carotenoids corresponds to reduced cancer risk ( 9 ).…”

C2orf40 inhibits hepatocellular carcinoma through interaction with UBR5

“…Hepatocellular carcinoma (HCC) is a common malignancy with the fifth incidence and the fourth mortality in the world 1 . Most of the patients cannot obtain good treatment due to inadequate diagnostic scheme and weak therapeutic target 2 . Therefore, it is critical to find a reliable biomarker for improving diagnosis and treatment of HCC.…”
