Trilostane (Win 24540) is a synthetic androstane derivative with adrenocortical suppressive properties, reversibly inhibiting 3 beta-hydroxysteroid dehydrogenase delta [5-4] isomerase in the adrenal cortex.

αVβ8-IN-1 is an αVβ8 integrin inhibitor that suppresses the growth of multiple tumour cell lines (EMT6, CT26, KPC, TKCC-10). It may be employed in research concerning tumours, idiopathic pulmonary fibrosis (IPF), non-specific interstitial pneumonia (NSIP), and other conditions.

Betamethasone 17-Propionate is a compound used in the study of its effects on endotoxin-induced uveitis in rats, capable of inhibiting cellular infiltration into the aqueous humor when administered topically or systemically at certain doses. However, compared to some other compounds, its inhibitory effects are relatively weaker. When administered systemically, the dosage is 1mg/kg. Additionally, in in vitro interleukin-8 (IL-8) release assays, Betamethasone 17-Propionate's suppression of IL-8 release from rat peritoneal exudate cells is less effective than that of betamethasone. Moreover, the concurrent addition of betamethasone dipropionate with Betamethasone 17-Propionate reduces the suppressive effects of betamethasone on cell infiltration and IL-1β gene expression.

CP-31398 stabilizes the active conformation of p53 in cancer cells with either mutated or wild-type p53, enhancing its activity. Additionally, CP-31398 upregulates target genes of p53 such as p21WAF1/Cip1 and KILLER/DR5. This compound possesses tumor-suppressive properties.

Cofpropamine, a caffeine derivative that inhibits polyadenylation, enhances the suppressive effects of Cyclophosphamide in animal models of rat adjuvant arthritis and mouse collagen-induced arthritis.

ST80 is an inhibitor of the interaction between OTUD4 and CD73. It decreases CD73 protein levels, enhances the turnover rate of CD73, and reduces immune evasion by tumor cells, thereby exhibiting antitumor effects against immune-suppressive triple-negative breast cancer (TNBC).

KCL-HO-1i is an orally active heme oxygenase-1 (HO-1) inhibitor with an IC50 of 123 nM for rat HO-1 and 128 nM for human HO-1. It targets immune-suppressive LYVE-1+ perivascular tumor-associated macrophages (PvTAMs) in the tumor microenvironment (TME) and reduces PvTAM-mediated immune evasion. In MMTV-PyMT mice with spontaneous breast cancer or C57Bl/6 mice with subcutaneous MN-MCA1 sarcoma, KCL-HO-1i demonstrates synergistic anti-tumor effects when combined with chemotherapy. It is applicable for cancer research.

ROCK2-IN-13 is a selective inhibitor of ROCK2. It functions by hindering ROCK2 kinase activity and reducing its nuclear expression, consequently disrupting the interaction between ROCK2 and transcription co-activators p300 and PGC 1α, thereby suppressing oncogene transcription. ROCK2-IN-13 activates FOXO1-driven PTEN expression, which in turn inhibits the PI3K/Akt pathway, induces G2/M cell cycle arrest, and promotes apoptosis (apoptosis). This compound effectively eliminates the nuclear transcription function of ROCK2 that maintains oncogenic signaling and restores the tumor-suppressive PTEN/FOXO1 axis. ROCK2-IN-13 is utilized in prostate cancer research.

XMU-MP-8 (SKPer1) is a potent molecular glue degrader that targets the oncogenic protein SKP2. It interacts with the F-box domain of SKP2 (Kd≈ 36 μM) and the N-terminal TPR domain of the E3 ligase STUB1 (Kd≈ 2.5 μM), leading to the formation of a stable SKP2-SKPer1-STUB1 ternary complex (Kd≈ 8.9 nM). This interaction triggers the ubiquitination and proteasomal degradation of SKP2. XMU-MP-8 selectively eradicates cancer cells expressing SKP2 and exhibits notable tumor-suppressive effects in vivo along with a favorable safety profile. It is applicable in research on cancers such as non-small cell lung adenocarcinoma (NSCLC) and prostate adenocarcinoma.

CG500354 plays a tumor suppressive role through the cAMP/CREB signaling pathway and is a novel inducer of neural differentiation and growth arrest in primary HUMAN GBM derived cells.

β-Endorphin (β-EP) is an endogenous opioid neuropeptide with diverse biological activities. It is produced via piomelanocortin cleavage in the pituitary gland, hypothalamus, and in lymphocytes, then migrates to its sites of action which include plasma, gut, skin, placenta, cerebrospinal fluid, and cardiac tissues. β-EP induces concentration-dependent decreases in electrically stimulated contraction of the mouse vas deferens that can be reversed by the μ-opioid antagonist CTP and δ-opioid antagonist ICI 174,864. In vivo, β-EP (5 μg, i.c.v.) slows gastrointestinal transit in mice. β-EP (0.5 or 5 μg, i.c.v.) stimulates food intake in rats for 4 to 6 hours, however, this effect is not prolonged with continuous infusion. It antagonizes the appetite-suppressive effects of α-melanocyte-stimulating hormone (α-MSH) for the first three days post administration. β-EP also reduces paralytic demyelination induced by the murine coronavirus MHV-JHM in immunocompetent, but not irradiated or immune-incompetent, mice and rats.
