3-Morpholinosydnonimine (SIN-1; Linsidomine) is a spontaneous ROS/RNS generator and a peroxynitrite donor. 3-Morpholinosydnonimine inhibits hypertrophic chondrocytes activity and induces necrosis. 3-Morpholinosydnonimine induces p53-dependent apoptosis, induces p53 accumulation and activates MAPK phosphorylation[1][2].
Kevetrin hydrochloride is a small molecule and activator of the tumor suppressor protein p53, with potential antineoplastic activity. Target：p53in vitro: Kevetrin activates p53 which in turn induces the expressions of p21 and PUMA (p53 up-regulated modulator of apoptosis), thereby inhibiting cancer cell growth and causing tumor cell apoptosis. Kevetrin may be effective in drug-resistant cancers with mutated p53. p53 tumor suppressor, a transcription factor regulating the expression of many stress response genes and mediating various anti-proliferative processes, is often mutated in cancer cells. in vivo: Kevetrin has demonstrated potent anti-tumor efficacy against various carcinoma xenograft models: lung, breast, colon, prostate and squamous cell carcinoma, and in a leukemia tumor model. In drug-resistant cell lines, Kevetrin has shown excellent activity, galvanizing the Company to focus on Kevetrin's development potential in this area.
KYP-2047 is a potent and BBB-penetrating prolyl-oligopeptidase (POP) inhibitor, with an Ki value of 0.023 nM. KYP-2047 reduces glioblastoma proliferation through angiogenesis and apoptosis modulation[1][2].
BI-0252 is an orally active, selective MDM2-p53 inhibitor with an IC50 of 4 nM. BI-0252 can induce tumor regressions in all animals of a mouse SJSA-1 xenograft, with concomitant induction of the tumor protein p53 (TP53) target genes and markers of apoptosis[1].
S-Propargylcysteine (SPRC), a structural analog of S-allyl cysteine (SAC), is a slow H2S-releasing compound. S-Propargylcysteine reduces Ca2+ accumulation and inflammatory cytokines, inhibits STAT3, and elevates p53 and Bax. S-Propargylcysteine has anti-inflammatory activity and protects mice against acute pancreatitis. S-Propargylcysteine also has cardioprotective, neuroprotective acitivties[1][2].
YH239-EE, ethyl ester of the free carboxylic acid compound YH239, is a potent p53-MDM2 antagonizing and apoptosis-inducing agentIC50 value:Target: MDM2/p53YH239-EE inhibits the growth of OCI-AML-3 cells with wild type p53 by inhibiting the p53-MDM2 interaction. YH239-EE induces cell cycle arrest and causes potent cell apoptosis via activation of p53 and downstream targets in four AML cells (OCI-AML-3 and MOLM-13 with wt p53, NB4 with p53 mutation, and HL60 with p53 deletion).
Anticancer agent 42 (compound 10d) is an orally active anticancer agent, and shows a potent antitumor activity against MDA-MB-231 cell with an IC50 of 0.07 μM. Anticancer agent 42 can exert its anticancer activity by activating apoptotic pathway and p53 expression. Anticancer agent 42 can be used to study metastatic breast cancer[1].
Lepadin E is a significantly cytotoxic ferroptosis inducer that induces iron death through the classical p53-SLC7A11-GPX4 pathway. Lepadin E promoted p53 expression, decreases SLC7A11 and GPX4 levels, and leads to increased ROS and lipid peroxide production, and upregulated ACSL4 expression, thus causes cell death. Lepadin E has significant antitumor effect[1].
COTI-2 is a small molecule candidate anti-cancer drug which can convert mutant p53 to wild-type conformation.
Verminoside is an iridoid isolated from Kigelia africana, exhibits anti-inflammatory and remarkable antioxidant activity with a radical-scavenging activity of 2.5 μg/mL. The genotoxicity of Verminoside on human lymphocytes is associated with elevated levels of PARP-1 and p53 proteins[1][2][3].
CTX1 is a novel small molecule p53 activator.
RG7112 is the first clinical and orally available MDM-2/p53 inhibitor designed to occupy the p53-binding pocket of MDM2, with the Kd value of 11 nM.
PRIMA-1 is a mutant p53 reactivator, restores the sensitivity of TP53 mutant-type thyroid cancer cells to the histone methylation inhibitor 3-Deazaneplanocin A.
Minocycline is an orally active, potent and BBB-penetrated semi-synthetic tetracycline antibiotic. Minocycline is a hypoxia-inducible factor (HIF)-1α inhibitor. Minocycline shows anti-cancer, anti-inflammatory, and glutamate antagonist effects. Minocycline reduces glutamate neurotransmission and shows neuroprotective properties and antidepressant effects. Minocycline inhibits bacterial protein synthesis through binding with the 30S subunit of the bacterial ribosome, resulting in a bacteriostatic effect[1][2][3][4][5][6][7].
