Chlorophyll Derivative

Chlorophyll breakdown products are usually studied for their antioxidant and anti-inflammatory activities. The chlorophyll derivative Pheophorbide a (PPBa) is a photosensitizer that can induce significant anti-proliferative effects in several human cancer cell lines. Cancer is a leading cause of death worldwide, accounting for about 9.6 million deaths, in 2018 alone. Hence, it is crucial to monitor emergent compounds that show significant anticancer activity and advance them into clinical trials. In this review, we analyze the anticancer activity of PPBa with or without photodynamic therapy and also conjugated with or without other chemotherapic drugs, highlighting the capacity of PPBa to overcome multidrug resistance. We also report other activities of PPBa and different pathways that it can activate, showing its possible applications for the treatment of human pathologies.

Sodium Copper Chlorophyllin

1. A condition that appears to be identical with ‘green yolks’ as observed in natural cases has been reproduced by the oral administration in gelatin capsule of from 250 to 1000 mg. sodium copper chlorophyllin 100% daily for 4 days upwards to Light Sussex hens in second lay.2. Following suitable extraction procedures the presence of a chlorophyll derivative has been determined spectrophotometrically in the affected yolks.3. Quantities of sodium copper chlorophyllin of the order of 1 mg. have been recovered from affected yolks.4. It is considered that the passage of chlorophyll to the yolk indicates that intestinal absorption has occurred.
