Prokineticin Receptor
Prokineticin Receptors (PKRs) are a class of G protein-coupled receptors comprising two subtypes, PKR1 and PKR2. They bind to endogenous ligands prokineticin (PK1 and PK2) and play pivotal roles in regulating various important physiological and pathological processes. Research has demonstrated that PKRs are critically involved in angiogenesis, neurogenesis, pain perception, reproductive functions, and circadian rhythm regulation[1].
PKR1 is primarily expressed in the cardiovascular system and peripheral tissues, where it participates in angiogenesis and cardioprotection, while PKR2 is predominantly distributed in the central nervous system, modulating neuronal development and synaptic plasticity . Upon activation, PKRs mainly signal through the Gq/11 protein-coupled pathway, stimulating phospholipase C (PLC) activation, which subsequently induces intracellular calcium release and protein kinase C (PKC) activation[2].

PKRA83
0 ImagesSynonyms: PKRA7PKRA83 (PKRA7) is a potent prokineticin (PK2) antagonist, which can compete for the binding of PK2 to its receptors PKR1 and PKR2. PKRA83 potently inhibits PK2 receptors, with IC50 values of 5.0 nM and 8.2 nM for PKR1 and PKR2, respectively. PKRA83 has anticancer, anti-arthritis and anti-angiogenic activities. .

7DG
0 ImagesSynonyms: 7-Desacetoxy-6,7-dehydrogedunin7DG (7-Desacetoxy-6,7-dehydrogedunin) is a PKR inhibitor, P2X7 purinergic receptor inhibitor, and skin-lightening agent. 7DG binds outside the ATP-catalytic domain of PKR, blocks the kinase activity-independent protein-protein interactions of PKR, inhibits the phosphorylation and activity of PKR, disrupts ASC assembly and caspase-1 activation, and suppresses the activation of the NLRP1 inflammasome. 7DG inhibits pyroptosis, suppresses the ATP-P2X7 signaling pathway, and abolishes ATP-induced increases in the expression levels of MITF, tyrosinase, PMEL/gp100, and melanin content. 7DG exerts skin-lightening effects in cultured skin in vitro. 7DG can be used in research related to chronic obstructive pulmonary disease, gout, type 2 diabetes, Alzheimer's disease, and hyperpigmentary skin disorders.
