HA155 is primarily utilized in research and development within the field of biochemistry and pharmacology. It serves as a potent and selective inhibitor of the enzyme soluble adenylyl cyclase (sAC), which plays a crucial role in cellular signaling pathways. By inhibiting sAC, HA155 is used to study the physiological and pathological processes regulated by cyclic AMP (cAMP), such as sperm motility, fluid secretion, and mitochondrial function. This compound is particularly valuable in investigating conditions like male infertility, glaucoma, and metabolic disorders. Additionally, HA155 aids in understanding the broader implications of cAMP signaling in various tissues and organs, contributing to the development of targeted therapeutic strategies. Its application extends to drug discovery efforts aimed at modulating sAC activity for treating related diseases.
