KH7 has been used:
  • as a soluble adenyl cyclase (sAC) antagonist to study its effect on the signaling pathway mediated by the action of transient  receptor type 1 (TRPV1) in sperm cells.
  • as a selective sAC antagonist to study its effect on the signaling pathway of proton gated channels (HV1) induced action in sperm cells.
  • as a sAC inhibitor to study its effects on cAMP increase in monophosphorylated myosin light chain (pMLC).

Biochem/physiol Actions

KH7 is a selective inhibitor of soluble adenylyl cyclase. Soluble adenylyl cyclase (sAC) is an ubiquitously expressed, essential component of cAMP-signaling.

In previous work, we reported that plasma membrane potential depolarization (PMPD) provokes cortical F-actin remodeling in bovine corneal endothelial (BCE) cells in culture, which eventually leads to the appearance of intercellular gaps. In kidney epithelial cells it has been shown...

β2-Aderenergic receptor (β2AR) agonist, Salmeterol exhibits anti-inflammatory activities. However, the inhibitory effects of Salmeterol on inflammasome activation are elusive and the underlying mechanisms need to be explored. In this study, we established inflammatory model in primary bone marrow-derived macrophages (BMDM)...

Both transcriptionally and translationally inactive sperm need preassembled pathways into specific cellular compartments to function. Although initiation of the acrosome reaction (AR) involves several signaling pathways including protein kinase A (PKA) activation, how these are regulated remains poorly understood in...

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.
