Oxybutynin chloride (Oxybutynin HCl) is an anticholinergic medication used to relieve urinary and bladder difficulties. It competitively antagonizes the M1, M2, and M3 subtypes of the muscarinic acetylcholine receptor.

Oxybutynin (Ditropan) is a synthetic anticholinergic agent that is used for treatment of urinary incontinence and overactive bladder syndrome.

Hymenidin HCl is a natural alkaloid isolated from Hymeniacidon sp. and acts as a serotonin (5-HT) receptor antagonist. Hymenidin HCl inhibits voltage-gated potassium channels (Kv), exhibits selective inhibition of CDK5, affects cellular signaling, and induces apoptosis in cancer cells.

Kv3 modulator 2 is a potent Kv3 channels modulator.has analgesic activity and is used in the prophylaxis or treatment of related disorders.

Kv3 modulator 3 is a selective modulator of Kv3.1 and or Kv3.2 and or Kv3.3 channels .has analgesic activity for use in the prophylaxis o or treatment of pain.

NADP+ is the oxidized form of the electron donor nicotinamide adenine dinucleotide phosphate . It serves as a cofactor in various biological reactions. In addition, the balance between these reduced and oxidized forms plays key roles in diverse cellular functions, including cell survival, the maintenance of redox status, and intracellular signaling. For example, binding of NADP+ to β-subunits of Kv channels activates ion transport, whereas NADPH stabilizes channel inactivation. NADP+ is biosynthesized from NAD+ by NAD kinase, with ATP as the phosphoryl donor.

Photoswitchable Kv channel blocker (IC50 values are 2 and 64 μM at 500 nm and 380 nm respectively). Switches conformation from cis to trans at 500 nm and trans to cis at 380 nm. Exhibits minimal activity at Nav1.2 and L-type Ca2+ channels. Stimulates action potential firing of hippocampal neurons in vitro at 500 nm and restores visual responsiveness in blind mice at 380 nm.

Kaliotoxin is an inhibitor of neuronal BK-type peptide groups and specifically inhibits Kv channels and calcium-activated potassium channels. Kaliotoxin has research significance on the regulation of cell membrane potential and neuronal excitability. The product number is T37808 and the CAS number is 145199-73-1

MSD-D is an inhibitor of voltage-gated K(+) (Kv) channels Kv1.5.

Phrixotoxin 2 selectively blocks the KV 4.2 and KV 4.3 channels, demonstrating high specificity in its interaction with these voltage-gated ion channels [1].

Aam-KTX, a toxic peptide sourced from Mesobuthus eupeus scorpion venom, acts as a selective K_v channel inhibitor, exhibiting IC_50 values of 1.1 nM for K_v1.3 channels and >750 nM for K_v1.1 channels. This compound shows promise for research in autoimmune diseases [1].

VSTx-3 is a potassium voltage-gated channel (K_V) blocker, which has also been shown to be a potent tetrodotoxin-sensitive (TTX-sensitive) sodium channel inhibitor, with particular efficacy against NaV1.8 channels, as evidenced by its half-maximal inhibitory concentration (IC_50) values of 0.19 μM for hNaV1.3, 0.43 μM for hNaV1.7, and 0.77 μM for hNaV1.8 channels.

LY303511, a structural analog of LY294002, selectively inhibits mTOR-dependent phosphorylation of S6K, unlike its counterpart, which acts as a phosphatidylinositol 3-kinase (PI3K) inhibitor. It effectively reduces cell proliferation in human lung epithelial adenocarcinoma cells by hindering G2 M phase progression and suppressing casein kinase 2 activity. Additionally, LY303511 enhances tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) sensitivity in HeLa cells resistant to TRAIL-induced apoptosis and blocks voltage-gated potassium (Kv) channels.

Halofuginone hydrochloride (RU-19110), a derivative of Febrifugine, functions as a competitive inhibitor of prolyl-tRNA synthetase, displaying a Ki value of 18.3 nM. This compound effectively inhibits type-I collagen synthesis, providing therapeutic benefits in osteoarthritis (OA) by impeding TGF-β signaling. Additionally, it serves as a potent pulmonary vasodilator, mainly through the activation of Kv channels and the inhibition of various calcium channels including voltage-gated, receptor-operated, and store-operated ones. Beyond its vascular effects, Halofuginone hydrochloride exhibits a broad spectrum of biological activities, including anti-malarial, anti-inflammatory, anti-cancer, and anti-fibrotic properties, supported by multiple studies.
