Pifithrin-α, p-Nitro, Cyclic (PFN-α) is a cell-permeable, active-form inhibitor of p53.

Inolitazone dihydrochloride is an effective, high-affinity PPARγ agonist; its biological activity is dependent on PPARγ (IC50:0.8 nM) to inhibit cell growth. Inolitazone dihydrochloride enhances the role of cell cycle kinase inhibitor p21 WAF1 CIP1.

Ivaltinostat (CG-200745) formic is an orally active pan-HDAC inhibitor with an isohydroxamic acid component that binds zinc at the bottom of the catalytic pocket. Ivaltinostat formic inhibits the deacetylation of histone H3 and tubulin, promotes p53 accumulation, induces p53-dependent transactivation, and enhances MDM2 and p21 (Waf1 Cip1) protein expression. It increases the sensitivity of Gemcitabine-resistant cells to Gemcitabine and 5-Fluorouracil (5-FU), induces apoptosis, and has antitumor effects.

1. Ginsenoside Rg5 could be a beneficial agent for the treatment of Alzheimer's disease. 2. Ginsenoside Rg5 suppresses LPS-induced nitric oxide (NO) production and proinflammatory TNF-α secretion. 3. Ginsenoside Rg5 can ameliorate lung inflammation possib

Pinoresinol ((+)-Pinoresinol) has antiinflammatory, hepatoprotective, and fungicidal activities, it can protect pial microcirculation from I-reperfusion injury, to increase nitric oxide release and to reduce oxidative stress preserving pial blood flow distribution; it may exert pharmacologically interesting effects via modulation of the insulin-like signalling pathway in C.elegans. Pinoresinol causes an upregulation of the CDK inhibitor p21(WAF1/Cip1) both at mRNA and protein levels, inhibits NF-kappaB and activating protein 1 (AP-1).

D-CopA3 is an inhibitor of MDM2 and an activator of the p53 signaling pathway. It exhibits cytotoxicity in colorectal cancer cells HCT-116, LoVo, and RKO with IC50 values of 15-18 μM and induces JNK Beclin-1 mediated autophagy. D-CopA3 downregulates the expression of the cell cycle inhibitor protein p21Cip1 Waf1, enhances mucosal barrier function, and reduces infiltration of inflammatory mediators. It shows anti-inflammatory properties in mouse models of acute enteritis induced by C. difficile toxin A and chronic colitis induced by DSS. Additionally, D-CopA3 demonstrates antitumor activity in a mouse HCT-116 xenograft model.
