Imiquimod (R 837) is an immune response modifier and a toll-like receptor 7 (TLR7) agonist with antiviral and antitumor effects. It is used in the study of external genital warts, perianal warts, cancer, and COVID-19, and is commonly employed to induce psoriasis models.

Famotidine (MK-208) is a propanimidamide and histamine H2-receptor antagonist with antacid activity. As a competitive inhibitor of histamine H2-receptors on the basolateral membrane of parietal cells, famotidine reduces basal and nocturnal gastric acid secretion, thereby decreasing gastric volume, acidity, and the amount of gastric acid released in response to various stimuli.

S-trityl-L-Cysteine is a non-natural amino acid and an inhibitor of Eg5, also known as KSP and Kif11, a mitotic kinesin necessary for mitotic spindle formation. S-trityl-L-Cysteine inhibits the ATPase activity of Eg5 in basal and microtubule-stimulated states (IC50s = 1,000 and 140 nM, respectively). It is selective for Eg5 over nine other human kinesins in an enzyme-coupled assay. It reversibly inhibits Eg5-driven microtubule sliding velocity with an IC50 value of 500 nM using X. laevis recombinant Eg5. It induces cell cycle arrest in HeLa cells (IC50 = 700 nM), reversibly halting the cell cycle in the mitotic phase by inhibiting the separation of duplicated chromosomes and preventing bipolar spindle formation. S-trityl-L-Cysteine inhibits the growth of cancer cells in vitro when tested against the National Cancer Institute (NCI) 60 human cancer cell line panel (average GI50 = 1.3 μM) and in mouse xenograft models.

Methyl Aminolevulinate Hydrochloride (5-Aminolevulinic acid methyl ester) is commonly used in photosentizer reagents for photodynamic therapy to treat conditions such as Acne vulgaris and hypertrophic scarring.

Pantoprazole sodium (Pantecta) is the sodium salt form of a substituted benzimidazole with proton pump inhibitor activity. Pantoprazole sodium is a lipophilic, weak base that crosses the parietal cell membrane and enters the acidic parietal cell canaliculus where it becomes protonated, producing the active metabolite sulfenamide, which forms an irreversible covalent bond with two sites of the H+/K+-ATPase enzyme located on the gastric parietal cell, thereby inhibiting both basal and stimulated gastric acid production.

HEPES is a zwitterionic sulfonic acid buffering agent, commonly used to uphold a neutral pH of basal medium within cell cultures.HEPES is a potent inducer of lysosome biogenesis.

LN-439A is a novel tetrahydro-β-carboline small molecule that acts as a potent catalytic inhibitor of the BAP1 deubiquitinase. It induces ubiquitination and degradation of the KLF5 transcription factor by binding to the catalytic pocket of BAP1. In basal-like breast cancer (BLBC) models, LN-439A significantly inhibits tumor cell proliferation and migration, induces G2/M phase arrest and apoptosis, and exhibits superior water solubility compared to existing BAP1 inhibitors. Furthermore, inhibition of BAP1 enzymatic activity by LN-439A also destabilizes its substrates, suggesting potential application value in inflammation-related diseases.

SBI-797812 is structurally similar to active-site directed inhibitor of NAMPT(NAMPT with EC50 of 0.37 μM).

Protoporphyrin IX disodium, as a radiation sensitizer, enhances the production of ROS and induces DNA damage even under hypoxic conditions. It also acts as a photosensitizer, undergoing direct degradation through photobleaching upon light exposure. This compound accumulates in rat tumor cells following administration of 5-aminolevulinic acid (5-ALA). When activated with a peak wavelength of 405 nm, Protoporphyrin IX disodium selectively improves basal cell carcinoma. It shows promise in pharmacological research of sonodynamic and photodynamic therapy for cancers such as bladder cancer and nodular basal cell carcinoma.

Pipinib is an ATP-competitive and selective phosphatidylinositol 4-kinase IIIβ (PI4KB) inhibitor with an IC50 value of 2.2 μM. Pipinib reduces intracellular PI4P levels and inhibits GLI-mediated transcription as well as the expression of Hedgehog target genes. Pipinib additionally blocks the trafficking of Smoothened to primary cilia. Pipinib is applicable to investigations involving basal cell carcinoma, medulloblastoma, Hedgehog signaling, and phosphoinositide-associated cellular regulation.

(Z)-Tyrphostin A51 is an isomer of Tyrphostin A51 exhibiting inhibitory activity against P. falciparum (IC₅₀≈10 μM).

AAA is an antagonist of G protein-coupled receptor 75 (GPR75).1It increases basal GPR75 protein levels and inhibits 20-HETE-induced reductions in GPR75 protein levels in PC3 cells. AAA (5 and 10 μM) also reduces 20-HETE-induced phosphorylation of EGFR, NF-κB, and Akt in, and cell migration of, PC3 cells.In vivo, AAA (10 mg/kg per day) reduces systolic blood pressure, albuminuria, renal angiotensin II levels, and cardiac hypertrophy in a Cyp1a1-Ren-2 transgenic rat model of malignant hypertension when administered prior to induction or after establishment of hypertension.2 1.Cárdenas, S., Colombero, C., Panelo, L., et al.GPR75 receptor mediates 20-HETE-signaling and metastatic features of androgen-insensitive prostate cancer cellsBiochim.

Dichloroacetate (DCA) is an inhibitor of all pyruvate dehydrogenase kinase (PDHK) isoforms, which are enzymes that phosphorylate and inhibit PDH in mitochondria. Inhibition of PDHK shifts cell metabolism from glycolysis to mitochondrial glucose oxidation, an effect that has relevance to cancer, type 2 diabetes, and other diseases. CAY10703 is a DCA trimer that is at least 10-fold more cytotoxic against leukemia cell lines than DCA. It is approximately 3-fold less cytotoxic than DCA against peripheral blood mononuclear cells from healthy blood donors. CAY10703 significantly reduces both basal and maximal respiration in leukemia cells. It is stable in vivo after subcutaneous inoculation, remaining in circulation for more than five hours after injection.

C2 Adamantanyl globotriaosylceramide (AdaGb3) is a bioactive sphingolipid and water-soluble form of globotriaosylceramide that contains an adamantanyl group in place of the fatty acyl chain. It inhibits Vero toxin binding to globotriaosylceramide in an ELISA assay when used at a concentration of 10 μM. AdaGb3 decreases cell surface expression of P-glycoprotein (P-gp) and reduces efflux of rhodamine 123 in MDCK cells. It also increases apical-to-basal transport of vinblastine in human intestinal C2BBe1 cells.

It exhibits IC50 values of 5, 46, 4, 11, and 8 nM for SYK, JAK1, JAK2, JAK3, and TYK2, respectively. This compound effectively and rapidly suppresses key inflammatory pathways involved in the pathogenesis of atopic dermatitis. Gusacitinib is also used in research for conditions such as chronic hand eczema and basal cell carcinoma.

Famotidine (Standard) is the standard substance of Famotidine, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Famotidine (MK-208) is a propanimidamide and histamine H2-receptor antagonist with antacid activity. As a competitive inhibitor of histamine H2-receptors located on the basolateral membrane of the parietal cell, famotidine reduces basal and nocturnal gastric acid secretion, resulting in a reduction in gastric volume, acidity, and amount of gastric acid released in response to various stimuli.

CJ28 is a cortisol biosynthesis inhibitor. In human adrenocortical carcinoma cell models, it significantly reduces cortisol production under both basal and stimulated conditions. The mechanism of action of CJ28 is primarily associated with the inhibition of the steroidogenesis pathway and de novo cholesterol biosynthesis, thereby reducing the supply of cortisol precursors and downregulating hormone synthesis levels.
