Oxysophocarpine is an alkaloid extracted from seaweed. It has neuroprotective and antinociceptive effects on the central and peripheral nervous systems.

CCR2-RA-[R] is a C-C chemokine receptor type 2 (CCR2) allosteric antagonist (IC50: 103 nM).

EF24 (3,5-Bis[(2-fluorophenyl)Methylene]-4-piperidinone) treatment increases the levels of activated caspase 3 and 9, and decreases the phosphorylated forms of MEK1 and ERK. EF24 shows potent anti-tumor activity in oral squamous cell carcinoma (OSCC) via deactivation of the MAPK/ERK signaling pathway.

GSK2643943A is a deubiquitylating enzyme (DUB) inhibitor, with an IC 50 of 160 nM for USP20/Ub-Rho. GSK2643943A has anti-tumor efficacy.

NSC745885 is an antitumor agent non-toxic to normal cells that downregulates EZH2 via proteasome-mediated degradation. It exhibits toxicity against multiple normal and drug-resistant cancer cell lines and may be used in studies of advanced bladder cancer and oral squamous cell carcinoma.

CXCR2-IN-3 is a CXCR2 inhibitor with an IC50 of 11.37 μM. It inhibits the CXCR2-Ca2+ signaling pathway, thereby blocking autophagic flux and promoting ROS-mediated apoptosis. Additionally, CXCR2-IN-3 suppresses the CXCR2-NLRP3 canonical pathway, reducing the expression of tumor-promoting markers. This compound induces autophagy-dependent cell death in polyploid giant cancer cells (PGCC) and is applicable in studies related to oral squamous cell carcinoma (OSCC).

HK2-IN-3 (compound 12) is a potent hexokinase 2 (HK2) inhibitor with an IC50 of 56.4 nM. It reduces glucose uptake and downregulates GLUT1/GLUT4 expression in oral squamous cell carcinoma (OSCC). HK2-IN-3 induces mitophagy (mitophagy) and apoptosis (apoptosis). In OSCC xenograft mouse models, HK2-IN-3 suppresses tumor growth and angiogenesis. It can be utilized in OSCC research.

β-Defensin-1 is a peptide with antimicrobial properties that protects the skin and mucosal membranes of the respiratory, genitourinary, and gastrointestinal tracts.1It inhibits the growth ofB. adolescentis,L. acidophilus,B. breve,B. vulgatus,L. fermentum,B. longum, andS. thermophilusin an antimicrobial radial diffusion assay.2β-Defensin-1 also inhibits the growth of periodontopathogenic and cariogenic bacteria, includingP. gingivalisandS. salivarius, and of susceptibleM. tuberculosisH37Rv but not of resistantM. tuberculosisRM22 when used at a concentration of 128 μg/ml.3,4It blocks human and mouse Kv1.3 voltage-gated potassium channels (IC50s = 11.8 and 13.2 μM, respectively).5Overexpression of β-defensin-1 in the human oral squamous cell carcinoma (OSCC) cell lines HSC-3, UM-1, and SCC-9 increases migration and invasion but not proliferation.6 1.Lehrer, R.I.Primate defensinsNat.

CAY10721 is an inhibitor of sirtuin 3 (SIRT3), a class III HDAC (39% SIRT3 inhibition at 200 μM). Upregulation of SIRT3 transcription is associated with oral squamous cell carcinoma (OSCC) and breast cancer with lymph node involvement, while SIRT3 down-regulation inhibits the growth of OSCC cells and sensitizes them to radiation and chemotherapy.

Artobiloxanthone (Compound AA3) exhibits antitumor activity, particularly against oral squamous cell carcinoma (OSCC). It inhibits the Akt/mTOR and STAT3 pathways, thereby suppressing the proliferation of SAS and T.Tn cells with IC50 values of 11 and 22 μM, respectively, as well as cancer cell migration. Artobiloxanthone induces cell apoptosis in OSCC by activating caspase3/9 and causes cell cycle arrest at the S phase.
