Apraclonidine HCl

Apraclonidine HCl (CAS No.: 73218-79-8) is a synthetic small molecule adrenergic modulator in the imidazoline related sympathomimetic class that is primarily categorized as a receptor pharmacology tool compound for ophthalmic and neurovascular research, with established activity as a selective alpha2 adrenergic receptor agonist and comparatively weaker alpha1 adrenergic receptor agonist that supports mechanistic investigation of presynaptic inhibitory signaling, modulation of cyclic AMP linked pathways, and downstream control of neurotransmitter release and vascular smooth muscle tone in ocular tissues; in biomedical discovery workflows it is commonly used to interrogate adrenergic regulation of aqueous humor dynamics and intraocular pressure associated phenotypes, and to benchmark alpha adrenergic pathway engagement in receptor profiling and phenotypic assay panels, while available literature descriptions generally indicate pharmacological activity detectable from nanomolar to micromolar concentration ranges depending on receptor context, assay format, and biological system, and experimental applications typically include in vitro studies in receptor expressing cell platforms, ex vivo ocular tissue preparations, and in vivo animal models designed to assess target engagement and physiology relevant to glaucoma associated biology, where the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives.
