Rapamycin and canagliflozin are capable to inhibit mTOR to promote lifespan. Atracurium, carnitine and statins act as DAF-16 activators, which potentially contribute to anti-ageing activity. Hydralazine, lisinopril, rosiglitazone and zidovudine may help stabilize genomic integrity to prolong life expectancy. Other indirect mechanisms, including insulin-lowering effect by acarbose and calcium channel blocking activity by verapamil may also promote longevity. Interestingly, some drugs (i.e., canagliflozin, metformin, rapamycin and acarbose) are likely to demonstrate a lifespan-promoting effect predominantly in male animals.

NPC has the ability to modify its metabolism and leads the patient to suffer from malnutrition and cachexia, therefore aggravates the occurrence of impaired inflammatory response. Currently, available treatments for NPC are chemotherapy, radiotherapy, or chemoradiotherapy. Despite of its efficacy, these regimens have been known to elicit various inflammation-related side effects including infection, diarrhea, and mucositis. It has long been established that increased activity of inflammatory response is associated to low survival rate in both early and advanced stage of cancer. Furthermore, uncontrolled and dysregulated inflammatory response are significantly correlated with malignant progression of cancer. Considering how pivotal inflammation to malignancy progression, there is a need for effective strategies to modulate inflammatory response. Various strategies have been proposed to improve immune response in NPC patients including dietary supplementation of synbiotics. Synbiotics refers to the manipulation of both probiotics and prebiotics to provide a synergistic benefit to the host by promoting the growth of beneficial bacteria while inhibiting the growth of pathogenic bacteria.
