Cancer Fighting Fish: Source of New Drugs?

 During the process known as metastasis, cancer cells detach from the bulk of the tumor and colonize distant organs. In order to do so, they enter the blood circulation by attaching to the cells that constitute tumor vessels. This event is driven by interactions occurring between Galβ1–3GalNAcα1-Ser/Thr, a disaccharide present on the surface of tumor cells, and galectin-3, a protein situated on vascular cells.

Garlic in India

 

 

Garlic in India

The ancient Indians had varying views on garlic; but, for the most part, it was considered to be highly beneficial to the body. Ancient Sanskrit writings, dating as far back as 5,000 years ago, described the healing properties of garlic. In fact, the ancient medical practice of Ayurveda, which is still practised today, promoted garlic as one of the most important herbs. It recommends garlic in over 100 formulations for treating stomach, liver, tumor, asthma and other similar problems.

The Charaka Samhita is the oldest surviving Ayurvedic text, dating back to 200 BCE to 200 CE (AD), and suggests using garlic for alleviating:

• worms
• piles
• leukoderma
• leprosy
• epilepsy
• heart disease
• fainting
• arthritis
• rheumatism
• chronic rhinitis
• baldness.

 It was also included in the diet of nursing mothers to encourage milk secretion in nursing mothers and was hung to protect against evil spirits.

Other Ayurvedic teachings recommend garlic for:

• arteriosclerosis
• pain
• cholera
• dysentery
• indigestion
• constipation
• appetite loss
• fatigue
• typhoid
• tuberculosis
• cough
• fractures. 

It is also advocated for improving eyesight, intelligence, sexual debility, and impotency.

On the other hand, the ancient Indians believed garlic was a natural aphrodisiac that inspired lust and stimulated passions and, as a result, holy men, monks, widows, adolescents, and fasting persons were forbidden from consuming garlic. In addition, it was considered to be rajasic food; which meant it had unsettling effects on the body and devotees on the path to spiritual enlightenment were advised against eating it. The Buddists, Jains, Greeks and Romans also shared these sentiments; however, some believe the mild irritation garlic caused in the genitourinary tract may have resulted in its aphrodisiac and rajasic status.

Chocolate as medicine: a quest over the centuries

The rehabilitation of chocolate has occurred only in recent times. The pages of scientific magazines have been positively recaptured and chocolate’s reputation is being restored to the value that Carl Linnaeus credited to this food, when he named the generous plant Theobroma cacao, the food of the gods

Alexion’s Soliris® (eculizumab) Receives Orphan Drug Designation for the Treatment of Neuromyelitis Optica (NMO)

Structure of eculizumab. Eculizumab was engineered to reduce immunogenicity and eliminate effector function. Human IgG2 and IgG4 heavy-chain sequences were combined to form a hybrid constant region that is unable to bind Fc receptors or to activate the complement cascade. Eculizumab exhibits high affinity for human C5, effectively blocking its cleavage and downstream proinflammatory and cell lytic properties. Reprinted from Rother et al with permission.

Eculizumab (INN and USAN; trade name Soliris) is a humanized monoclonal antibody that is a first-in-class terminal complement inhibitor and the first therapy approved for the treatment of paroxysmal nocturnal hemoglobinuria (PNH), a rare, progressive, and sometimes life-threatening disease characterized by excessive destruction of red blood cells (hemolysis). It costs £400,000 (US$600,000) per year per patient

Eculizumab also is the first agent approved for the treatment of atypical hemolytic uremic syndrome (aHUS), an ultra-rare genetic disease that causes abnormal blood clots to form in small blood vessels throughout the body, leading to kidney failure, damage to other vital organs and premature death.

In clinical trials in patients with PNH, eculizumab was associated with reductions in chronic hemolysis, thromboembolic events, and transfusion requirements, as well as improvements in PNH symptoms, quality of life, and survival.Clinical trials in patients with aHUS demonstrated inhibition of thrombotic microangiopathy (TMA),the formation of blood clots in small blood vessels throughout the body, including normalization of platelets and lactate dehydrogenase (LDH), as well as maintenance or improvement in renal function.

Eculizumab was discovered and developed by Alexion Pharmaceuticals and is manufactured by Alexion. It was approved by the United States Food and Drug Administration (FDA) on March 16, 2007 for the treatment of PNH, and on September 23, 2011 for the treatment of aHUS. It was approved by the European Medicines Agency for the treatment of PNH on June 20, 2007, and on November 24, 2011 for the treatment of aHUS. Eculizumab is currently being investigated as a potential treatment for other severe, ultra-rare disorders.
