Nemorosone is a polycyclic polyprenylated acylphloroglucinol (PPAP) originally isolated from C. rosea that has antiproliferative properties.1 Nemorosone inhibits growth of NB69, Kelly, SK-N-AS, and LAN-1 neuroblastoma cells (IC50s = 3.1-6.3 μM), including several drug-resistant clones, but not MRC-5 human embryonic fibroblasts (IC50 = >40 μM).2 It increases DNA fragmentation in LAN-1 cells in a dose-dependent manner, and decreases N-Myc protein levels and phosphorylation of ERK1/2 by MEK1/2. Nemorosone also inhibits growth of Capan-1, AsPC-1, and MIA-PaCa-2 pancreatic cancer cells (IC50s = 4.5-5.0 μM following a 72-hour treatment) but not human dermal and foreskin fibroblasts (IC50s = >35 μM).1 It induces apoptosis, abolishes the mitochondrial membrane potential, and increases cytosolic calcium concentration in pancreatic cancer cells in a dose-dependent manner. Nemorosone activates the caspase cascade in a dose-dependent manner and inhibits cell cycle progression, increasing the proportion of cells in the G0/G1 phase, in both neuroblastoma and pancreatic cancer cells.1,2 Nemorosone (50 mg/kg, i.p., per day) also reduces tumor growth in an MIA-PaCa-2 mouse xenograft model.3References1.

MRK003 is a γ-secretase inhibitor exhibits promising in vitro pre-clinical activity in multiple myeloma and non-Hodgkin's lymphoma. MRK003 treatment induced caspase-dependent apoptosis and inhibited proliferation of MM and NHL cell lines and patient cells. Examination of signaling events after treatment showed time-dependent decrease in levels of the notch intracellular domain, Hes1 and c-Myc. MRK003 downregulated cyclin D1, Bcl-Xl and Xiap levels in NHL cells and p21, Bcl-2 and Bcl-Xl in MM cells. In addition, MRK003 caused an upregulation of pAkt, indicating crosstalk with the PI3K/Akt pathway.

CBP EP300-IN-2 is an inhibitor of CBP EP300 with IC50 values of 1.07 nM for CBP HTRF and 5.96 nM for Myc.

PROTAC BRD4 Degrader-8 is a potent BRD4 inhibitor with IC50 values of 1.1 nM and 1.4 nM for BRD4 BD1 and BD2, respectively, effectively degrading the BRD4 protein in PC3 prostate cancer cells[1].

Idarubicin, a potent anthracycline antileukemic agent, is orally active in its application. It functions by inhibiting topoisomerase II, thus interfering with DNA replication and RNA transcription. Furthermore, Idarubicin induces DNA damage, inhibits DNA synthesis, and suppresses c-myc expression. It also demonstrates inhibitory effects on the growth of bacteria and yeasts [1] [2] [3] [4] [5].
