RosA, Rosmarinic acid: Click to Expand ⟱
Features: polyphenol
Polyphenol of many herbs - rosemary, perilla, sage mint and basil. Rosmarinic acid (RA) is predominantly found in a variety of medicinal and culinary herbs, especially those belonging to the Lamiaceae family, including rosemary (Rosmarinus officinalis), basil (Ocimum basilicum), sage (Salvia officinalis), thyme (Thymus vulgaris), and mints (Mentha spp.). In addition to the Lamiaceae family, RA is also present in plants from other families, such as Boraginaceae and Apiaceae.
-Rosmarinic acid is one of the hydroxycinnamic acids, and was initially isolated and purified from the extract of rosemary, a member of mint family (Lamiaceae)
-Its chemical structure allows it to act as a free radical scavenger by donating hydrogen atoms to stabilize ROS and free radicals.
RA’s dual nature as both a phenolic acid and a flavonoid-related compound enables it to chelate metal ions and prevent the formation of free radicals, thus interrupting oxidative chain reactions. It can modulate the activity of enzymes involved in OS, such as catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx), underscoring its potential role in preventing oxidative damage at the cellular level.
-divided as rosemary extract, carnosic acid, rosmarinic acid?

Summary:
-Capacity to chelate transition metal ions, particularly ironChelator (Fe2+) and copper (Cu2+)
-RA plus Cu(II)-induced oxidative DNA damage, which causes ROS
-rosmarinic acid (RA) as a potential inhibitor of MARK4↓ (inhibiting to tumor growth, invasion, and metastasis) activity (IC50 = 6.204 µM)

-Note half-life 1.5–2 hours.
BioAv water-soluble, rapid absorbtion

P53, P53-Guardian of the Genome: Click to Expand ⟱
Source: TCGA
Type: Proapototic
TP53 is the most commonly mutated gene in human cancer. TP53 is a gene that encodes for the p53 tumor suppressor protein ; TP73 (Chr.1p36.33) and TP63 (Chr.3q28) genes that encode transcription factors p73 and p63, respectively, are TP53 homologous structures.
p53 is a crucial tumor suppressor protein that plays a significant role in regulating the cell cycle, maintaining genomic stability, and preventing tumor formation. It is often referred to as the "guardian of the genome" due to its role in protecting cells from DNA damage and stress.
TP53 gene, which encodes the p53 protein, is one of the most frequently mutated genes in human cancers.
Overexpression of MDM2, an inhibitor of p53, can lead to decreased p53 activity even in the presence of wild-type p53.
In some cancers, particularly those with mutant p53, there may be an overexpression of the p53 protein.
Cancers with overexpression: Breast, lung, colorectal, overian, head and neck, Esophageal, bladder, pancreatic, and liver.

eff↑, Chitosan was chosen as a nanodrug delivery in our research as per our aim, and we intended to offer a locally acting formula that may be applicable in managing oral cancerous lesions. Chitosan has a penetration capability as it is able to open tight
BioAv↑, chitosan nanoparticles, an increase in the surface-to-volume ratio occurs as well as the specific surface area. This enhances the dissolution of poorly water-soluble drugs so increases their bioavailability.
