Spirulina platensis with bioactive compounds such as Phycocyanin, β-carotene, Genistein and α-glucan, have been shown to have anti-inflammatory properties. Our present study investigation utilizes an in silico methodology to examine the molecular interactions between Spirulina platensis chemicals compound with TNFa and p21. Utilizing computational techniques molecular docking, our goal is to clarify the possible pathways by which Spirulina platensis chemicals could affect these important regulators and postpone cellular senescence. Our research may shed important light on the creation of Spirulina platensis-based therapies for ageing and age-related illnesses. Our results imply that Spirulina platensis may contribute to overall cellular health and the mitigation of cellular senescence. Phycocyanin has the most negative ΔG value is -15.0 kcal/mol. Genistein has the lowest Ki value, namely 7.299 μM. The ΔG and Ki values of Genistein were lower than Quercetin. The potential chemical interactions between substances generated from Spirulina platensis and senescence pathways, including those involving TNFa and p21, are highly intriguing for the development of innovative therapeutic approaches targeted at ameliorating cellular senescence dysfunction associated with aging.

Graptophyllum pictum (L.) Griff., a shrubby stove plant, has been used traditionally to treat various diseases. This review summarizes the up-to-date data about its phytochemistry and pharmacological properties and provides a perspective and direction for future research. The phytochemical analysis of G. pictum revealed the presence of flavonoids, steroids, glycoside, tannins, saponin, chlorophyll, nontoxic alkaloid, and anthocyanin. Meanwhile, the pharmacological analysis revealed that this plant possessed various activities such as antimicrobial, immunomodulatory, antioxidant, anti-inflammation, anti-analgetic, woundhealing, anti-hemorrhoid, anti-diabetic, and estrogenic effects. However, most of its pharmacological activities were based on the crude extracts and the bioactive compounds responsible for the bioactivities have not been well identified. A further detailed investigation in phytochemistry to identify the bioactive compounds and to investigate the mechanism action of its bioactivities is required. Moreover, a toxicology study is also needed to develop a standardized formulation of G. pictum preparation and to fulfill the requirements of modern phytomedicine.
