Clinical Tagline
Selective CGRP receptor modulator engineered to suppress neurogenic inflammation while preserving neurovascular stability and systemic homeostasis.
Biomedical Translation Source
Calcitonin Gene-Related Peptide (CGRP) — a 37-amino acid neuropeptide widely expressed in sensory neurons; central mediator of:
- Neurogenic inflammation
- Vasodilation
- Pain transmission (trigeminal pathways)
- Immune–vascular signaling
Ethnobioprospecting Source
- Functional analog mapping from pain-modulating and anti-inflammatory ethnomedical systems:
- Traditional Chinese Medicine (meridian-based pain regulation; Qi stagnation resolution)
- Amazonian medicine (plant alkaloids modulating nociception and vascular tone)
- Ayurveda (anti-inflammatory and migraine-modulating botanicals such as Tanacetum parthenium analogs)
Source Description
CGRP is a central neurovascular-inflammatory mediator, linking sensory neuron activation to immune and vascular responses. Dysregulation results in:
- Chronic migraine
- Neuroinflammation
- Peripheral sensitization
Ethnomedical systems historically target this axis through pain-relieving and anti-inflammatory compounds, indirectly modulating CGRP signaling.
Source Region
Endogenous human peptide system; ethnomedical analogs derived from East Asia, South America, and South Asia.
Theory (SCF Therapeutic Innovation)
Neuroinflammatory disorders are driven by overactivation of CGRP signaling, leading to:
- Vasodilatory instability
- Immune cell recruitment
- Chronic nociceptive signaling
- Trigeminal pathway sensitization
CGRP-ANTX7 is engineered to selectively modulate CGRP receptor activity, suppressing pathological signaling while preserving:
- Baseline vascular tone
- Protective neuropeptide functions
Hypothesized API Therapeutic Concept
CGRP-ANTX7 functions as a selective CGRP receptor antagonist/modulator that:
- Inhibits CALCRL/RAMP1 receptor activation
- Reduces neurogenic inflammation
- Dampens trigeminal nociceptive signaling
- Prevents vascular over-suppression (balanced modulation)
