What is CBDA?

5-HT1A RECEPTORS

This receptor is pivotal in various physiological processes, including mood regulation, anxiety, and the vomiting reflex. CBDA functions as an indirect agonist for these receptors. Research indicates significant potential in treating nausea and vomiting, particularly in chemotherapy-induced nausea where conventional treatments may be ineffective or have undesirable side effects. CBDA has been shown to be about a hundred times more effective than CBD in reducing nausea and vomiting in animal models.³ This efficacy is mirrored in the receptor's role in anxiety, where low doses of CBDA have been shown to reduce anxiety in stressed mice, highlighting its potential as an anxiolytic agent.⁴

TRP CHANNELS

CBDA acts on Transient Receptor Potential (TRP) channels, which are involved in sensing temperature, pain, and pressure. CBDA's interaction with these channels, particularly TRPV1, is believed to mediate its analgesic and anti-inflammatory effects. Given TRP channels' role in pain perception and inflammation, CBDA's action on these channels could offer a non-opioid alternative for chronic and inflammatory pain management. This is supported by studies showing CBDA's enhanced potency over CBD in mouse models for pain and inflammation, suggesting a direct therapeutic application in conditions like arthritis and neuropathic pain.⁵

ANANDAMIDE (AEA) REUPTAKE

Although not directly interacting with a specific receptor, CBDA influences the endocannabinoid system by blocking the uptake of anandamide, thereby increasing its availability and effects. Anandamide is a naturally occurring endocannabinoid that binds to cannabinoid receptors, with roles in pain, mood, and appetite regulation. By enhancing anandamide levels, CBDA may contribute to the potentiation of its analgesic and mood-enhancing effects. This mechanism could offer therapeutic benefits in conditions characterized by chronic pain or mood disorders, extrapolating from the known effects of anandamide on these physiological states.⁶

2-AG Synthesis Inhibition

CBDA inhibits the synthesis of 2-Arachidonoylglycerol (2-AG), another endocannabinoid that plays a role in energy balance, immune function, and insulin sensitivity. The inhibition of 2-AG synthesis by CBDA may have therapeutic implications for obesity and metabolic disorders, including insulin resistance. Given 2-AG's involvement in energy homeostasis and the promotion of obesity when overproduced, CBDA's regulatory effect could represent a novel approach to managing these conditions, potentially improving insulin sensitivity and reducing obesity-related inflammation.⁶

COX Enzymes Inhibition

Similar to nonsteroidal anti-inflammatory drugs (NSAIDs), CBDA inhibits cyclooxygenase (COX) enzymes, particularly COX-2, which are involved in the inflammatory process. This inhibition can decrease the production of prostaglandins, compounds that promote inflammation, pain, and fever. Beyond its implications for managing pain and inflammation, COX-2 inhibition by CBDA has been explored for its potential to reduce breast cancer cell metastasis, offering a novel avenue for cancer therapy through the modulation of gene expression related to cancer cell proliferation and metastasis.⁷
