Activators & Inhibitors

Alfuzosin hydrochloride (Alfuzosin HCl) is an α1 adrenergic receptor antagonist. It applies to treat benign prostatic hyperplasia (BPH).

Antazoline hydrochloride (Phenazoline hydrochloride), a first-generation antihistamine, can bind to the histamine H1 receptor and block the action of endogenous histamine.

Sorafenib tosylate (Bay 43-9006) is a potent multikinase inhibitor (IC50s: 6/20/22 nM for Raf-1/VEGFR-3/B-Raf).

Sorafenib (Bay 43-9006) is a multikinase inhibitor that targets Raf-1, B-Raf, VEGFR2, VEGFR3, VEGFR4, PDGFRβ, FLT3, c-Kit, and others (IC50=6/22/90/15/20/20/57/58 nM) with oral activity. It exhibits antitumor properties and can induce autophagy, apoptosis, and agonistic iron death.

Bendamustine hydrochloride (EP-3101) (IC50 of 50 μM) is an alkylating agent associated with DNA damage.

Vardenafil (Vivanza) is an oral therapy for the treatment of erectile dysfunction. It is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). Penile erection is a hemodynamic process initiated by the relaxation of smooth muscle in the corpus cavernosum and its associated arterioles. During sexual stimulation, nitric oxide is released from nerve endings and endothelial cells in the corpus cavernosum. Nitric oxide activates the enzyme guanylate cyclase resulting in increased synthesis of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the corpus cavernosum. The cGMP in turn triggers smooth muscle relaxation, allowing increased blood flow into the penis, resulting in erection. The tissue concentration of cGMP is regulated by both the rates of synthesis and degradation via phosphodiesterases (PDEs). The most abundant PDE in the human corpus cavernosum is the cGMPspecific phosphodiesterase type 5 (PDE5); therefore, the

Through its effects on ULK1 and ULK2, MRT67307 blocks autophagy. MRT67307 prevents the phosphorylation of IRF3 and the production of IFN-β and increases toll-like receptor-induced IL-10 and IL-1ra secretion in macrophages. MRT67307 is a kinase inhibitor that has been shown to inhibit TBK1, MARK1-4, IKKε, and NUAK1 (IC50 values are 19, 27-52, 160, and 230 nM, respectively), the salt-inducible kinases (SIKs; IC50s =250, 67, and 430 nM for SIK1, SIK2, and SIK3, respectively) and ULK1 and ULK2 (IC50s = 45 and 38 nM, respectively).

Pazopanib (GW786034) is an inhibitor of protein tyrosine kinases that inhibits VEGFR1, VEGFR2, VEGFR3, PDGFRβ, c-Kit, FGFR1, and c-Fms (IC50=10/30/47/84/74/140/146 nM). Pazopanib has antitumor activity.

Ipratropium bromide monohydrate (Ipratropium bromide hydrate) is a muscarinic antagonist structurally related to ATROPINE but often considered safer and more effective for inhalation use. It is used for various bronchial disorders, in rhinitis, and as an antiarrhythmic.
