1. 2,5-Dihydroxyacetophenone (Quinacetophenone) possess anti-anxiety, and neuroprotective qualities. 2. 2,5-Dihydroxyacetophenone (Quinacetophenone) reatment can induce a sustained activation of JNK, ERK1 2, and p38 MAPKs, it also can potentiate the pro-apoptotic and anti-proliferative effects of bortezomib in U266 cells. 3. 2,5-Dihydroxyacetophenone (Quinacetophenone) has anti-inflammatory activity in activated macrophages, raising the possibility that this compound has a therapeutic potential for inflammatory conditions. 4. 2,5-Dihydroxyacetophenone (Quinacetophenone) is an uncompetitive inhibitor of murine tyrosinase (K(I) 0.28mm), it strongly inhibits both melanogenesis and cellular tyrosinase activity in vitro in 3-isobutyl-1-methylxanthin-stimulated B16 mouse melanoma cells or in vivo in zebrafish and mouse models.

Cladribine (2CdA), an adenosine deaminase inhibitor, is utilized in the treatment of lymphoproliferative diseases.

AVN-944 (VX-944)(VX-944) is a selective, noncompetitive inhibitor of human IMPDH with Ki of 6-10 nM for IMPDH1 IMPDH2.

GSK126 (GSK2816126A) is a excellently specific EZH2 methyltransferase inhibitor ( IC50=9.9 nM).

Iberdomide (CC-220) is a modulator of cereblon( IC50 value of 60 nM in a competitive TR-FRET assay).

JRN73958 is an important precursor for the synthesis of scytonemin, also called Reduced scytonemin. Scytonemin is a biological pigment synthesized by many strains of cyanobacteria, including Calothrix sp., Lyngbya aestuarii, and others. Scytonemin is also a potent PKL1 inhibitor, which inhibits cell proliferation and arrests cell cycle through downregulating Plk1 activity in many cancel cells. Scytonemin was able to inhibit the proliferation of three myeloma cells in a dose-dependent manner, while U266 was the most sensitive one to scytonemin. Scytonemin , representing a novel Plk1 inhibitor, induced the inhibition of cell growth and cell cycle arrest in multiple myeloma cells by specifically decreasing Plk1 activity. This product has no formal name at the moment. For the convenience of communication, a temporary code name was therefore proposed according to MedKoo Chemical Nomenclature (see web page: https: www.medkoo.com page naming).

Dimethylmatairesinol can reduce the amount of Immunoglobulin E (IgE) secreted by human myeloma U266 cells, it has potential as an anti-allergic agent. Dimethylmatairesinol also exhibits significant cytotoxicity against three human tumor cells(A-549 lung c

8-Chloroadenosine (NSC-354258) is a 5' AMP-activated protein kinase agonist potentially for the treatment of chronic lymphocytic leukemia. 8-chloroadenosine activity is associated with inhibition of the mTOR pathway.8-Chloroadenosine (NSC-354258) is a nucleoside analog; metabolized in vivo to 8-Chloro-ATP. Incorporates into RNA during transcription and inhibits RNA synthesis. Exhibits cytotoxicity in MM.1S, RPMI-8226, and U266 cancer cell lines; induces G2 M cell cycle arrest and mitotic catastrophe in A549 and H1299 cells. 8-Chloroadenosine (NSC-354258) has been shown to deplete ATP and inhibit tumor growth in hematological malignancies as well as in lung and breast cancer cell lines.

Nifuroxazide-d4 is intended for use as an internal standard for the quantification of nifuroxazide by GC- or LC-MS. Nifuroxazide is a nitrofuran antibiotic. It is active against strains of the enteropathogenic bacteria C. jejuni, Salmonella, Y. enterocolitica, Shigella, and E. coli. It inhibits quorum sensing and virulence factor production in P. aeruginosa. Nifuroxazide inhibits STAT3 activity in a reporter assay and decreases viability of U266 and INA-6 myeloma cells, which have constitutive STAT3 phosphorylation, with EC50 values of approximately 4.5 µM for both. It also decreases viability, migration, and invasion of, and induces apoptosis in, MCF-7, 4T1, and MDA-MB-231 breast cancer cells. Nifuroxazide reduces tumor growth and prevents pulmonary metastasis in a 4T1 murine mammary carcinoma model. It also reduces diarrhea, weight loss, and colon inflammation in a rat model of acetic acid-induced ulcerative colitis.

HDAC6-IN-18 (Compound 4), an irreversible and selective HDAC6 isoform inhibitor, exhibits potent anti-multiple myeloma effects. It demonstrates HDAC6 inhibitory activity with IC50 values of 0.17, 0.7, and 0.42 μM in RPMI8266, U266, and MM.1S cells, respectively [1].
