Prostaglandin E1 (Alprostadil) is the naturally occurring prostaglandin E1 (PGE1) which displays a variety of pharmacologic actions. Prostaglandin E1 is a potent vasodilator agent that increases peripheral blood flow, inhibits platelet aggregation, and induces bronchodilation. Used in the treatment of erectile dysfunction, this agent produces corporal smooth muscle relaxation by binding to PGE receptors, resulting in the activation of adenylate cyclase and the subsequent accumulation of 3'5'-cAMP.

Dacisteine (N,S-Diacetyl-L-cysteine) is an inhibitor of New Delhi metallo-beta-lactamase-1 (NDM-1) with an IC50 of 1000 μM.

Limaprost (17α,20-dimethyl-δ2-PGE1) is an analog of PGE1 with structural modifications intended to give it a prolonged half-life and greater potency.It is a potent and orally active vasodilator. Limaprost increases blood flow and inhibits platelet aggregation. Limaprost (17α,20-dimethyl-δ2-PGE1) can be used for pain relief, has antianginal effects, and has potential for ischaemic symptoms treatment.

MY-5445 (N-(3-chlorophenyl)-4-phenylphthalazin-1-amine) is a specific inhibitor of phosphodiesterase type 5 (PDE5). MY-5445 selectively inhibits cGMP PDE (Ki:1.3 μM).

Parmodulin 2 (ML 161) is the inhibitor of protease-activated receptor 1 (PAR1)-mediated platelet activation (IC50: 0.26 μM for the inhibition of platelet P-selectin expression on human platelets). It also inhibits thrombin-induced platelet activation.

R59949 is used as a Diacylglycerol kinase (DGK) inhibitor.

Jujuboside B has potent inhibitory effects on collagen-, thrombin-, AA-, and ADP-induced aggregation, and also exhibits superior protection on the thromboembolic model.

1. Neobavaisoflavone is isolated as a DNA polymerase inhibitor. 2. Neobavaisoflavone might be a potential anabolic agent to treat bone loss-associated diseases. 3. Neobavaisoflavone has anti-inflammatory activity, can significantly inhibit the production

RHC 80267 (U-57908) is a selective inhibitor of DAGL, with an IC50 of 4 μM in canine platelets.

SC99 is a selective inhibitor of JAK2-STAT3 activation. SC99 downregulates the expression of STAT3-modulated genes.SC99 inhibits platelet activation, aggregation and displays potent anti-myeloma, anti-thrombotic activities

Sulfuretin is a potent anti-oxidant, has protective effect against t-BHP-induced oxidative damage in human liver-derived HepG2 cells is attributable to its ability to scavenge ROS and up-regulate the activity of HO-1 through the Nrf2/ARE and JNK/ERK signa

Homoeriodictyol 7-O-β-D-glucoside (Homoeriodictyol 7-O-glucoside) is a natural product derived from Viscum coloratum (Kom.) Nakai and acts as an antagonist of platelet-activating factor (PAF).

GPRP acetate (Pefabloc FG) is fibrinogen-related peptides, which inhibit the interaction of fibrinogen with the platelet membrane glycoprotein IIbIIIa complex (GPIIbIIIa).

Platelet aggregation-IN-3 (Compound 5) acts as a ligand for H2 histamine receptors, α2(A,C)-adrenergic receptors (α2-AR), and 5-HT2(B,C) serotonin receptors. This compound can inhibit platelet aggregation induced by ADP and collagen, and it also modulates tumor cell-induced platelet aggregation (TCIPA).
