Summary
Researchers developed new histamine derivatives that selectively activate carbonic anhydrase I (CA I). These compounds offer potential for cognitive enhancement and Alzheimer
Area of Science:
- Biochemistry
- Pharmacology
- Medicinal Chemistry
Background:
- Histamine exhibits biological activity, including effects on carbonic anhydrase (CA).
- CA inhibition is pharmacologically relevant for various conditions, but CA activation is underexplored for cognitive enhancement.
- Diminished CA activity is reported in conditions like Alzheimer's disease.
Purpose of the Study:
- To synthesize novel ureido and bis-ureido histamine derivatives.
- To investigate the potential of these derivatives as activators of carbonic anhydrase isoforms.
- To identify selective CA activators for potential therapeutic applications.
Main Methods:
- Synthesis of ureido and bis-ureido histamine derivatives via reaction with isocyanates.
- Assay of synthesized derivatives for carbonic anhydrase (CA) activating effects.
- Testing against human carbonic anhydrase isoforms (hCA I and hCA II).
Main Results:
- A series of ureido and bis-ureido histamine derivatives were successfully prepared.
- The derivatives demonstrated activating effects exclusively on the human carbonic anhydrase I (hCA I) isoform.
- No significant effect was observed on the human carbonic anhydrase II (hCA II) isoform.
Conclusions:
- This study reports the first identification of selective CA I activators.
- These novel compounds may serve as valuable tools for elucidating the physiological roles of CA I.
- The findings open avenues for exploring CA I activation in cognitive enhancement and neurodegenerative diseases.

Drugs that mimic the action of endogenous catecholamines like noradrenaline and adrenaline are called adrenergic agonists or sympathomimetics. Based on their mechanism of action, sympathomimetics can be classified as direct-, indirect-, or mixed-acting sympathomimetics. Direct-acting adrenergic agonists activate adrenoceptors without affecting presynaptic neurons, making them independent of neuronal catecholamine-depleting agents like reserpine and guanethidine.

2.7K
Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...

Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of...

Aquaporins or AQPs are a family of integral membrane proteins whose primary function is to transport water, while some called aquaglyceroporins also transport glycerol. In addition, aquaporins have also been suspected to be involved in transporting volatile substances, such as carbon dioxide and ammonia, across membranes. Such AQPs that act as gas channels are often highly expressed in cells involved in the gaseous exchange, such as red blood cells, epithelial cells, and pulmonary capillaries.

The renin-angiotensin-aldosterone system (RAAS) is an intricate physiological pathway involving numerous enzymes and hormones, including renin, angiotensin-converting enzyme (ACE), angiotensin I and II, and aldosterone. Imbalances within this system increase the production of angiotensin II and aldosterone. Increased angiotensin II levels promote vasoconstriction and blood pressure elevation. Concurrently, higher aldosterone levels stimulate sodium and water reabsorption in the kidneys,...
