Extracted from the core of sandalwood bushes (santalum album tree), sandalwood oil has been used for a lot of centuries by a number of cultures all through the world for fragrance, soaps, incense and candles. With its earthy candy scent, this important oil is also used within the meals trade and topically in numerous beauty preparations.
Importantly, this pure oil is understood for its well being advantages and medicinal purposes from antibacterial to anticancer due to its phytochemical constituents. Along with containing esters, free acids, aldehydes, ketones and santenone, sandalwood oil primarily (90 p.c or extra) constitutes santalol – equal quantities of two compounds, alpha and beta-santalol.
Now, researchers from Florida Atlantic College’s Schmidt Faculty of Medication and collaborators are the primary to display in vivo the chemo-preventive properties of alpha-santalol towards prostate most cancers improvement utilizing a transgenic mouse mannequin.
Outcomes of the examine, revealed within the journal
Phytomedicine Plus
, confirmed that administration of alpha-santalol decreased the incidence of prostate tumors by reducing cell proliferation and inducing apoptosis, with out inflicting weight reduction or any noticeable uncomfortable side effects. Apoptosis, or programmed cell dying, is a technique the physique makes use of to eliminate unneeded or irregular cells equivalent to most cancers cells.
Findings revealed that the world occupied by regular tissue in alpha-santalol-treated mice was 53 p.c in comparison with 12 p.c in management mice. This means that administering alpha-santalol protected the traditional tissue and delayed development from prostatic intraepithelial neoplasia, a precancerous situation, to poorly differentiated carcinoma, a high-grade type of most cancers the place most cancers cells and tissue look very irregular. These outcomes are vital as a result of mortality in prostate most cancers sufferers is principally attributable to superior levels of the illness.
In prior research, the researchers demonstrated the efficacy of alpha-santalol in suppressing progress and inducing apoptotic cell dying in cultured human prostate most cancers cells. Based mostly on these observations, they chose a genetically engineered mouse mannequin that resembles many options just like human prostate most cancers, eliciting totally different lesion grades and most cancers development.
“Though our mobile research supplied vital mechanistic insights, related in vivo fashions are very important for growing novel chemo-preventive brokers for scientific use and to find out if alpha-santalol presents safety towards prostate most cancers improvement,” stated Ajay Bommareddy, Ph.D., senior creator and an affiliate professor of pharmacology within the Division of Biomedical Science, FAU Schmidt Faculty of Medication. “Previous to this new examine, alpha-santalol’s in vivo efficacy towards prostate most cancers improvement had not but been established.”
Further findings of the present examine confirmed alpha-santalol diminished the incidence of seen prostate tumors in comparison with control-treated mice. Solely 11 p.c within the handled group developed prostate tumors whereas greater than half within the management group developed the tumors. The variations in urogenital and prostate weights had been statistically considerably totally different in alpha-santalol-treated mice in contrast with controls. The common moist weight of urogenital tract in alpha-santalol handled mice was about 74.28 p.c decrease in contrast with management mice. Equally, the common moist weight of the prostate gland was decrease by 52.9 p.c in contrast with management mice.
Prostate most cancers is the second main explanation for most cancers dying in males in america. An estimated 288,300 new circumstances had been recognized in American males final 12 months with about 34,700 estimated deaths.
Present remedy strategies for prostate most cancers embody androgen ablation, chemotherapy, radiotherapy and radical prostatectomy, however are ineffective towards superior prostate cancers. Early detection and native remedy have resulted in improved outcomes however has been difficult with the administration of superior levels.
“Figuring out brokers which have the power to selectively goal cancerous cells and delay onset and development of prostate most cancers is significantly wanted,” stated Bommareddy. “Further research are important to systemically discover the feasibility of alpha-santalol as a promising chemo-preventive and anti-tumor agent towards human prostate most cancers improvement and to elucidate the mechanisms surrounding the position of pro-apoptotic and antiapoptotic proteins.”
