Applications of butylidenephthalide (BP), comprising the use of BP in providing a kit for promoting differentiation of stem cells into brown adipose cells, and the use of BP in preparing a medicament, wherein the medicament is used for inhibiting the accumulation of white adipose cells, promoting the conversion of white adipose cells into brown adipose cells, inhibiting weight gain and/or reducing the content of triglycerides, glucose, and total cholesterol in blood.

The present disclosure provides use of a combination of acyclovir and dexamethasone (DXMT) in preparation of a drug for treating Alzheimer's disease (AD); where the use includes all symptoms of a patient with the AD, especially following symptoms: cognitive impairment and neuroinflammation. Combination of the acyclovir and the DXMT has a synergistic effect, to exert anti-inflammatory and immunoregulation effects to achieve a therapeutic effect.

Compositions and methods are presented that help reduce cellular ageing, improve cellular stress resilience, and/or promote increased longevity. Exemplary compositions include a combination of a purine alkaloid, an isothiocyanate or thioglucoside, a metal-containing antioxidant, and optionally an additional ingredient, where the purine alkaloid, the isothiocyanate or thioglucoside, and the metal-containing antioxidant may be chemically isolated compounds or extracts or other preparations from naturally occurring entities such as plants, bacteria, yeast, etc. Advantageously, contemplated compositions are effective to reduce and repair oxidative stress, improve mitochondrial function, augment DNA repair and telomere maintenance, increase fatty acid metabolism, and modulate histone deacetylation. More specifically, the contemplated compositions are capable of increasing cellular vitality by inducing expression of OCT4, SOX, and/or KLF4 and/or decreasing biomarkers of cell senescence.

A human dietary supplement comprises theacrine and optionally other compounds that modulate the effects of theacrine. Uses for the theacrine-containing supplement include improvement of at least one of mood, energy, focus, concentration or sexual desire or a reduction of at least one of anxiety or fatigue. A synergistic composition comprises co-administration of theacrine and caffeine, wherein the co-administered caffeine reduces theacrine oral clearance (CL/F) and oral volume of distribution (Vd/F). In addition, the co-administered caffeine increases area under the plasma concentration time curve (AUC) of theacrine, and increases theacrine maximum plasma concentration (C.sub.max) in comparison with the corresponding pharmacokinetic parameters when theacrine is administered alone.
