Reconstitution Note ARA-290 is supplied in a PBS-buffered formulation (Phosphate Buffered Saline). Due to its amphipathic nature, the peptide may exhibit self-association, leading to increased viscosity or gel-like behavior during or after reconstitution. To reduce gelification risk: use adequate solvent volume (avoid high concentrations), mix gently, allow equilibration at room temperature, and apply slight warming if needed. Check solvent pH and adjust with buffer (e.g., PBS) if required. Prepare fresh solutions and avoid prolonged storage. These behaviors are not uncommon for amphipathic peptides and do not necessarily indicate product instability or degradation.ARA-290 has been investigated in preclinical and experimental research models designed to study inflammatory, metabolic, vascular, and neurobiological mechanisms relevant to the following disease-related research contexts: Cardiovascular-related experimental modelsRetinal ischemia and microvascular injury models Peripheral nerve injury and neuropathy models Small fiber nerve degeneration models Chronic inflammatory joint disease models Renal inflammation and metabolic stress models Hepatic lipid accumulation and inflammatory liver models Intestinal inflammation models Systemic autoimmune and immune dysregulation models Wound healing and tissue repair models

VIP (Vasoactive Intestinal Peptide) is a 28–amino acid neuropeptide of the secretin–glucagon family, widely expressed in the brain, gastrointestinal tract, pancreas, lungs, heart, thyroid, adrenal glands, and thymus. It acts through the GPCR receptors VPAC1 and VPAC2, activating cAMP-related signaling pathways that regulate vascular tone, immune balance, secretion mechanisms, and neuronal survival. Research suggests VIP has neuroprotective and neurotrophic properties, supporting blood–brain barrier integrity, reducing oxidative stress, and modulating neuroinflammation, with relevance in neurodegenerative models such as Alzheimer’s and Parkinson’s disease. VIP also regulates circadian rhythm via hypothalamic signaling, supports gastrointestinal motility and barrier integrity, and has immunomodulatory effects by reducing pro-inflammatory cytokines and promoting immune tolerance. Additional studies indicate antifibrotic and vasodilatory activity relevant to cardiovascular and pulmonary disease models, as well as potential relevance in transplantation tolerance research and lacrimal secretion regulation in dry eye-related conditions.
