Research Interests

 

Project 1

Cytidine-5’-Diphosphocholine (CDP–Choline or Citicoline) in Stroke and other CNS Disorders

CDP-choline improved the outcome of patients in phase III clinical trials of stroke. It was shown to have beneficial effects in a number of CNS injury models. AlText Box:  though experimental evidence is limited, the therapeutic action of CDP-choline is thought to be due to stimulation of phosphatidylcholine (PC) synthesis in a damaged brain. Understanding the actions of CDP-choline could lead to development of more efficient treatment strategies for ischemia/reperfusion injury. Our studies of transient cerebral ischemia suggest that CDP-choline might enhance reconstruction (synthesis) of PC and sphingomyelin. CDP-choline could also act by inhibiting destructive processes (activation of phospholipases). The major mechanism of action of CDP-choline may be in modulating activation of phospholipase A2 (PLA2) (Scheme 1).

 

Integration of cytokine biology and lipid metabolism: CDP-choline beneficial effects could be attributed to interactions at TNF-α/IL-1 mediated events, differentially affecting phospholipases and CCT. This limits phospholipid hydrolysis and increases synthesis, thereby restoring PC and SM levels (Scheme. 2). Our recent studies also showed that PC loss is a cause rather than a result of cell death. Since all cells (neurons, astrocytes, and endothelial cells etc., called the ‘neurovascular unit’) contain PC as a membrane building block, CDP-choline protection may arise from stabilizing the ‘neurovascular unit’. These studies provide an integration of CDP-choline effects with cytokine biology and lipid metabolism in stroke.

CDP-CHOLINE IN STROKE CLINICAL TRIALS:

What factors might be critical?

Virtually no side effects and is well tolerated in stroke clinical trials.

Recent phase III stroke clinical studies by Davalos et al (Stroke 2002) showed that CDP-choline is effective in stroke

 

 

 

 

 

 

 

 

In light of these developments, future studies are warranted to further confirm the efficacy of CDP-choline for stroke treatment.

Route of administration is critical.

         Route of administration: Oral (USA) vs i.v. (non-USA).

         Brain uptake of CDP-choline, 0.5% (oral) vs 2% i.v.

         Liposome encapsulated CDP-choline (brain uptake 23%) attenuated cerebral infarction better than other routes (ip and iv) of administration.

 

 

Up-date on CDP-choline Clinical Trials

·            IVAX, a Florida based company, in agreement with Grupo Ferrer (Barcelona, Spain) is filing for FDA approval of CDP-choline for acute stroke treatment.

·            Elder Pharmaceuticals (Mumbai, India) with Grupo Ferrer (Barcelona, Spain) launched CDP-choline (Somazina) phase III clinical trials for acute stroke treatment in India.

Project 2.

Phosphatidylcholine Homeostasis in Stroke

Significance: Tumor necrosis factor-α (TNF-α) and interleukin-1 (IL-1) are major pro-inflammatory cytokines and are rapidly up-regulated in brain after cerebral ischemia. Blockade of TNF-α by administration of TNF-α antibodies (TNF-α ab) or TNF-α binding protein attenuated ischemic brain injury in a number of studies. Transgenic mice deficient in both IL-1α and IL-1ß showed dramatic reduction in infarcts compared to wild-type mice. Similarly, treatment with IL-1 receptor antagonist (IL-1ra) reduced neuronal death in all forms of experimental cerebral ischemic injury.

TNF-α and IL-1 disrupt PC homeostasis (Scheme 3): In vitro studies have shown that PLA2 and PC-phospholipase C (PC-PLC) are induced by TNF-α and mediate their cytotoxicity. Activation of PLA2 by TNF-α/IL-1 may be mediated by increases in PLA2 activating protein (PLAP). PLAP in the rat brain has been characterized, but its role in cerebral ischemia has not been explored. PLA2 and PC-PLC hydrolyze PC, the major membrane phospholipid. PC loss is sufficient in itself to induce cell death. We have shown stimulation of PLA2, significant loss of phospholipids including PC  and significant decrease in cytidine triphosphate phosphocholine cytidylyltransferase (CCT) activity following transient brain ischemia.

PC synthesis: TNF-α and IL-1 inhibit CCT, the rate-limiting enzyme in PC synthesis. Thus these two proinflammatory cytokines may simultaneously stimulate PC hydrolysis and inhibit its synthesis (Scheme 2).

CDP-choline, formed by CCT, is the rate-limiting intermediate in the PC synthesis. Cholinephosphotransferase (CPT) catalyzes ultimate step of making PC from CDP-choline and 1,2-diacylglycerol. We have shown that CDP-choline treatment attenuated PLA2 activity, loss of CCT activity, hydroxyl radical (OH•) generation, lipid peroxidation, phospholipid hydrolysis and showed significant neuroprotection after transient cerebral ischemia.

Project 3

Polyamines in Stroke

Polyamines (putrescine, spermidine and spermine) are ubiquitous cellular components. The role of alterations in polyamine metabolism in neuronal degeneration after CNS injury remains an unresolved issue. Polyamines are important in the stabilization of cellular components such as cell membranes and chromatin structures; depletion of polyamines could lead to loss of cell integrity and cell death. Transient cerebral ischemia results in loss of spermine and spermidine. Our research seeks to determine whether normalization of the transient, ischemia–induced polyamine imbalance is neuroprotective. Spermine is considered to be an antioxidant and free radical scavenger, and restoring its levels may protect the brain from oxidative damage (either by scavenging hydroxyl radical or chelating Fe2+) following ischemia/reperfusion (Scheme 4).
