Uses
Different sources of media describe the Uses of 114528-79-9 differently. You can refer to the following data:
1. (-)-U-50488 Hydrochloride is an analgesic agent used in the protection of ischemia/ischemia reperfusion.
2. (?)-trans-(1S,2S)-U-50488 hydrochloride hydrate (U-50488) has been used as a κ-opioid receptor (KOR) agonist has been used to study its effect on the increase of tidal volumes in adult red-eared slider turtles (Trachemys scripta).
Biological Activity
(-)-u-50488 hydrochloride is a selective agonist for κ-opioid receptor [1].the κ-opioid receptor (kor) is a type of opioid receptor for opioid peptide dynorphin and controls addiction. also, kor plays an important role in stress, anxiety, anhedonia, depression and increased drug-seeking behavior.(-)-u-50488 hydrochloride is a selective kor agonist [1]. in isolated rat drg neurons, u-50488 (0.3-40 μm) inhibited voltage-independent ca2+ channel currents. in hela cells that didn’t express kor, u-50488 (20 μm) blocked ca2+ channels [2].in rhesus monkeys, u-50488 exhibited potent antinociceptive activity and produced diuresis [1]. u-50488 enhanced contraction of the rabbit vas deferens induced by electrically with ic50 value of 26.5 nm. in mice, u-50488 impaired motor function with ed50 value of 15.3 mg/kg and reduced spontaneous activity [3]. in adult rats, u-50488 increased the threshold required to maintain self-stimulation responding, a depressive-like effect. while, males were significantly more sensitive than females to the threshold-increasing effects [4].
Biochem/physiol Actions
Potent κ opioid receptor agonist; more potent enantiomer of (±)-trans-U-50488.

Check Digit Verification of cas no
The CAS Registry Mumber 114528-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,5,2 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 114528-79:
(8*1)+(7*1)+(6*4)+(5*5)+(4*2)+(3*8)+(2*7)+(1*9)=119
119 % 10 = 9
So 114528-79-9 is a valid CAS Registry Number.

Optimisation of the Anti-Trypanosoma brucei Activity of the Opioid Agonist U50488

Screening of the Sigma-Aldrich Library of Pharmacologically Active Compounds (LOPAC) against cultured Trypanosoma brucei, the causative agent of African sleeping sickness, resulted in the identification of a number of compounds with selective antiproliferative activity over mammalian cells. These included (+)-(1R,2R)-U50488, a weak opioid agonist with an EC50 value of 59nM as determined in our T.brucei invitro assay reported previously. This paper describes the modification of key structural elements of U50488 to investigate structure-activity relationships (SAR) and to optimise the antiproliferative activity and pharmacokinetic properties of this compound.
