Ethaverine hydrochloride alters cochlear microcirculation, intracochlear Po₂, CM potential, and EP in guinea pigs, and induces transient hypotension. Ethaverine hydrochloride is used in the research of peripheral vascular diseases.

Amg-1 is a potent, reversible and selective indoleamine 2,3-dioxygenase (IDO1) inhibitor (IC₅₀ = 3.0 μM). Amg-1 exhibits >80-fold selectivity over IDO2 (IC₅₀ > 250 μM) and >20-fold selective over TDO (IC₅₀ > 62.5 μM). Amg-1 can be used for cancer, hypotension, and neurological disorders research.

Azapetine is an antagonist of α₁-adrenoceptor, with an IC₅₀ of 0.205 μM at rat α₁-adrenoceptor and an IC₅₀ of 1.3 μM at rat α₂-adrenoceptor, and exhibits higher selectivity for α₁-adrenoceptor than for α₂-adrenoceptor. Azapetine functionally blocks postsynaptic α₁-adrenoceptors, and at higher concentrations, it blocks presynaptic α₂-adrenoceptors, central α-adrenoceptors, and H₂ histamine receptors. Azapetine is used in related research on hypotension.

Cyclocarioside K is a triterpene glycoside compound that can be naturally extracted from the dried leaves of Cyclocarya paliurus (Batal.) Iljinsk (Chinese wingnut) from Bozhou, Anhui, China. The leaves of this plant are traditionally used to lower blood sugar and blood pressure.

PPM-18 (NSC 73233) is a Vitamin K (HY-B2172) analog. PPM-18 prevents LPS-induced IκBα degradation, thereby inhibiting NF-κB activation and nuclear translocation of NF-κB. PPM-18 inhibits LPS-induced nitrite production and iNOS expression. PPM-18 inhibits HDAC6. PPM-18 induces ROS accumulation, activates AMPK, inhibits the mTORC1 and PI3K/AKT pathways, initiates Autophagy, and induces Apoptosis. PPM-18 suppresses seizures in zebrafish and mouse epilepsy models. PPM-18 prevents LPS-induced lethal toxicity and delayed hypotension. PPM-18 exhibits anticancer activity against leukemia and bladder cancer. PPM-18 can be used in research related to septic shock, bladder cancer and atherosclerosis.

Azapetine phosphate is an antagonist of α₁-adrenoceptor, with an IC₅₀ of 0.205 μM at rat α₁-adrenoceptor and an IC₅₀ of 1.3 μM at rat α₂-adrenoceptor, and exhibits higher selectivity for α₁-adrenoceptor than for α₂-adrenoceptor. Azapetine phosphate functionally blocks postsynaptic α₁-adrenoceptors, and at higher concentrations, it blocks presynaptic α₂-adrenoceptors, central α-adrenoceptors, and H₂ histamine receptors.

B 4310 is a non-organ-selective Bradykinin antagonist. B 4310 induces uterine contraction in rats. B 4310 blocks bradykinin-mediated responses, including substance P release, plasma extravasation, venous contraction, prostaglandin E₂ release and trigeminal nerve stimulation, but exerts no effect on angiotensin II, acetylcholine or capsaicin pathways. B 4310 exerts a reversible antagonistic effect on bradykinin-induced nociceptors. B 4310 serves as a tool for investigating the biological effects of bradykinin.

Arecaidine-propargyl ester is a selective M2 muscarinic receptor agonist with blood-brain barrier permeability, with a pK_i of 5.91 for hm1, 7.06 for hm2, 6.07 for hm3, 6.01 for hm4, and 6.03 for hm5. Arecaidine-propargyl ester stimulates central and peripheral muscarinic receptors. Arecaidine-propargyl ester increases intracellular ROS, induces DNA damage and Apoptosis, and upregulates the expression of MnSOD and SIRT1. Arecaidine-propargyl ester reduces sympathetic nerve outflow, induces dose-dependent hypotension, and triggers negative chronotropic effects at high peripheral doses. Arecaidine-propargyl ester can be used in research related to Alzheimer's disease and glioblastoma.
