MAPK Signaling

Tauroursodeoxycholate (Tauroursodeoxycholic acid; TDUCA) dihydrate is an endoplasmic reticulum (ER) stress inhibitor. Tauroursodeoxycholate significantly reduces expression of apoptosis molecules, such as caspase-3 and caspase-12. Tauroursodeoxycholate also inhibits ERK.

MW-150 dihydrochloride dihydrate (MW01-18-150SRM dihydrochloride dihydrate) is a selective, CNS penetrant, and orally active inhibitor of p38α MAPK with a Ki of 101 nM.

4-Hydroxylonchocarpin is a chalcone compound from an extract of Psoralea corylifolia.

Actein is a triterpene glycoside isolated from the rhizomes of Cimicifuga foetida. Actein suppresses cell proliferation, induces autophagy and apoptosis through promoting ROS/JNK activation, and blunting AKT pathway in human bladder cancer. Actein has little toxicity in vivo.

Asperulosidic Acid (ASPA), a bioactive iridoid glycoside, is extracted from the herbs of Hedyotis diffusa Willd.

Belvarafenib TFA (HM95573 TFA) is a potent and pan RAF (Rapidly Accelerated Fibrosarcoma) inhibitor, with IC50s of 56 nM, 7 nM and 5 nM for B-RAF, B-RAFv600E and C-RAF respectively.

A biflavonoid with diverse biological activities

Bisabolangelone, a sesquiterpene derivative, is isolated from the roots of Osterici Radix.

Bucladesine calcium salt salt (Dibutyryl-cAMP calcium salt;DC2797 calcium salt) is a cell-permeable cyclic AMP (cAMP) analog and selectively activates cAMP dependent protein kinase (PKA) by increasing the intracellular level of cAMP.

Chicanine is a lignan compound of Schisandra chinesis, inhibits LPS-induced phosphorylation of p38 MAPK, ERK 1/2 and IκB-α, with anti-inflammatory activity.

CHMFL-EGFR-202 is a potent, irreversible inhibitor of epidermal growth factor receptor (EGFR) mutant kinase, with IC50s of 5.3 nM and 8.3 nM for drug-resistant mutant EGFR T790M and WT EGFR kinases, respectively. CHMFL-EGFR-202 exhibits ?10-fold selectivity for EGFR L858R/T790M against the EGFR wild-type in cells. CHMFL-EGFR-202 adopts a covalent “DFG-in-C-helix-out” inactive binding conformation with EGFR, with strong antiproliferative effects against EGFR mutant-driven nonsmall-cell lung cancer (NSCLC) cell lines.

Cobimetinib hemifumarate is a novel selective MEK1 inhibitor, and the IC50 value against MEK1 is 4.2 nM.

Cot inhibitor-1 (compound 28) is a selective tumor progression loci-2 (Tpl2) kinase inhibitor with an IC50 of 28 nM.

Cot inhibitor-2 is a potent, selective and orally active cot (Tpl2/MAP3K8) inhibitor with an IC50 of 1.6 nM. Cot inhibitor-2 inhibts TNF-α production in LPS-stimulated human whole blood with an IC50 of 0.3 μM.

An alkaloid with diverse biological activities

ERK5-IN-2 is an orally active, sub-micromolar, selective ERK5 inhibitor with IC50s of 0.82 μM, 3 μM for ERK5 and ERK5 MEF2D, respectively.

Thalidomide-O-PEG4-amine is a synthesized E3 ligase ligand-linker conjugate that incorporates the Thalidomide based cereblon ligand and a linker used in PROTAC technology.

FTI 276 TFA is a protein farnesyl transferase (PFT) inhibitor with an IC 50 value of 1nM.
