UCSF924NC is the recommended negative control compound for the high-affinity dopamine D4 receptor (DRD4) partial agonist UCSF924. UCSF924NC exhibits a 1 2500-fold reduced D4 affinity when compared with that of UCSF924.
Azalanstat HCl is an anti-obesity drug acting as a lanosterol 14α-demethylase inhibitor. Azalanstat HCl has been shown to inhibit cholesterol synthesis in HepG2 cells, human fibroblasts, hamster hepatocytes and hamster liver, by inhibiting the cytochrome P450 enzyme lanosterol 14 alpha-demethylase. When administered orally to hamsters fed regular chow, RS-21607 (50 mg kg day) lowered serum cholesterol in a dose-dependent manner (ED50 = 62 mg kg) in a period of 1 week. It preferentially lowered low density lipoprotein (LDL) cholesterol and apo B relative to high density lipoprotein (HDL) cholesterol and apo A-1.
Chemodosimeter 1 is designed as a highly selective phosphate ion (PI) sensor capable of demonstrating exogenous and endogenous ATP-catalysed PI production and is the first probe capable of tracking PI production and enrichment through half-channel closure
UR-PI376 is a histamine H4 receptor agonist (hH4R agonist) (pEC50 = 7.47, alpha = 0.93), with low activity for hH1R and hH2R and significant selectivity for hH3R (pKB = 6.00, alpha =- 0.28), as in stable-use a membrane preparation of hH(x)R-expressing Sf9
Destruxin B2 is a cyclic hexadepsipeptide mycotoxin that has been found in M. anisopliae and has antiviral, insecticidal, and phytotoxic activities.1,2,3 It inhibits secretion of hepatitis B virus surface antigen (HBsAg) by Hep3B cells expressing hepatitis B virus (HBV) DNA (IC50 = 1.3 μM).1 Destruxin B2 is toxic to Sf9 insect cells in an electric cell-substrate impedance sensing (ECIS) test with a 50% inhibitory concentration (ECIS50) value of 92 μM.4 It is also phytotoxic to B. napus leaves.3 |1.

Tenellin is a fungal metabolite that inhibits Mg2+-, Ca2+-, and Na+ K+-ATPase activities in erythrocytes. Tenellin is cytotoxic to Sf9 and Sf21 insect cells.
Bassianin, a fungal metabolite identified in Beauveria, demonstrates inhibition of Mg2+-, Ca2+-, and Na+/K+-ATPase activities in equine erythrocyte ghosts, with inhibition rates of 81%, 58%, and 23%, respectively, at a concentration of 200 µg/ml. Additionally, bassianin exhibits cytotoxic properties against Sf9 and Sf21 insect cells, with 50% cytotoxic concentration (CC50) values of 4.91 µM and 12.12 µM, respectively.
