| α-Bisabolol — α-Bisabolol is a naturally occurring monocyclic sesquiterpene alcohol best known as a major bioactive constituent of chamomile essential oil, especially German chamomile (Matricaria chamomilla / Matricaria recutita) and related chamomile preparations. It is a small lipophilic phytochemical classified as a plant-derived essential-oil terpene alcohol, with common abbreviations including α-BSB, BSB, and levomenol for the (-)-α-bisabolol enantiomer. In oncology research it is mainly a preclinical pro-apoptotic and anti-invasive compound with preferential mitochondrial stress effects in cancer models; in clinical deployment it remains a cosmetic/natural-health constituent rather than an approved anticancer drug. -The main components in German chamomile are terpenoid; α-bisabolol and its oxide azulenes, such as chamazulene (1–15%); and apigenin. Roman chamomile, on the other hand, contains mainly angelic acid and tiglic acid esters. Apigenin is a main bioactive component and considered a quality marker of chamomile.Primary mechanisms (ranked):
Bioavailability / PK relevance: α-Bisabolol is highly lipophilic and poorly water soluble, so systemic translation depends strongly on formulation, route, dose, and vehicle. Essential-oil or neat-compound exposure does not imply predictable plasma exposure, and advanced delivery systems such as cyclodextrin complexes, nanoemulsions, or lipid carriers may be required for reproducible systemic or CNS delivery. In-vitro vs systemic exposure relevance: Most anticancer findings use direct in-vitro exposure at micromolar to high-micromolar concentrations, often with solvent-assisted delivery. These concentrations may exceed achievable free systemic exposure after ordinary chamomile tea, dietary chamomile, or topical/cosmetic use. Chamomile oil composition is also chemotype-dependent, so α-bisabolol content can vary substantially. Clinical evidence status: Cancer evidence is preclinical only. There are human trials of α-bisabolol-containing topical products for non-cancer indications, and chamomile has natural-health/traditional-use monographs for digestive, inflammatory gastrointestinal, and calmative uses, but there is no established human oncology indication, no approved anticancer label, and no cancer RCT evidence for α-bisabolol or chamomile oil. Mechanistic Profile
TSF legend: P: 0–30 min; R: 30 min–3 hr; G: >3 hr Alzheimer’s disease relevance: α-Bisabolol has meaningful preclinical AD relevance through amyloid-β toxicity reduction, mitochondrial protection, anti-inflammatory activity, oxidative-stress reduction, and possible cholinesterase-related effects. Evidence includes Aβ-induced cell and animal/C. elegans models, scopolamine-memory models for α-bisabolol derivatives, and chamomile essential-oil studies with α-bisabolol-rich composition. However, there is no established human AD clinical evidence for α-bisabolol, and brain exposure is likely formulation-dependent because the compound is lipophilic and poorly water soluble. |

| Also known as CP32. Cysteinyl aspartate specific proteinase-3 (Caspase-3) is a common key protein in the apoptosis and pyroptosis pathways, and when activated, the expression level of tumor suppressor gene Gasdermin E (GSDME) determines the mechanism of tumor cell death. As a key protein of apoptosis, caspase-3 can also cleave GSDME and induce pyroptosis. Loss of caspase activity is an important cause of tumor progression. Many anticancer strategies rely on the promotion of apoptosis in cancer cells as a means to shrink tumors. Crucial for apoptotic function are executioner caspases, most notably caspase-3, that proteolyze a variety of proteins, inducing cell death. Paradoxically, overexpression of procaspase-3 (PC-3), the low-activity zymogen precursor to caspase-3, has been reported in a variety of cancer types. Until recently, this counterintuitive overexpression of a pro-apoptotic protein in cancer has been puzzling. Recent studies suggest subapoptotic caspase-3 activity may promote oncogenic transformation, a possible explanation for the enigmatic overexpression of PC-3. Herein, the overexpression of PC-3 in cancer and its mechanistic basis is reviewed; collectively, the data suggest the potential for exploitation of PC-3 overexpression with PC-3 activators as a targeted anticancer strategy. Caspase 3 is the main effector caspase and has a key role in apoptosis. In many types of cancer, including breast, lung, and colon cancer, caspase-3 expression is reduced or absent. On the other hand, some studies have shown that high levels of caspase-3 expression can be associated with a better prognosis in certain types of cancer, such as breast cancer. This suggests that caspase-3 may play a role in the elimination of cancer cells, and that therapies aimed at activating caspase-3 may be effective in treating certain types of cancer. Procaspase-3 is a apoptotic marker protein. Prognostic significance: • High Cas3 expression: Associated with good prognosis and increased sensitivity to chemotherapy in breast, gastric, lung, and pancreatic cancers. • Low Cas3 expression: Linked to poor prognosis and increased risk of recurrence in colorectal, hepatocellular carcinoma, ovarian, and prostate cancers. |
