Synthesis of 5-aminolevulinic acid derivatives for photodynamic therapy

, 2012
The aim of the thesis was to synthesize a new derivative of 5-aminolevulinic acid, a prodrug used in current photodynamic therapy of cancer. To improve the bioavailability of 5-aminolevulinic acid the new derivative is conceived as an ester instead of an

Hepatic 5-aminolevulinic acid synthase mRNA stability is modulated by inhibitors of heme biosynthesis and by metalloporphyrins

, 2008
Hepatic 5-aminolevulinic acid synthase, the first and normally rate-controlling enzyme of heme biosynthesis, is regulated by heme. One of the known mechanisms whereby increased cellular heme regulates 5-aminolevulinic acid synthase is by decreasing the ...

Effect of 5-aminolevulinic acid on yield and quality of lettuce in sunlit greenhouse

, 2016
The role of 5-aminolevulinic acid (ALA) as a precursor of chlorophyll and heme is well documented. Low concentration of exogenous ALA has been found to regulate plant growth and increase crop yield, but there is little information on how ALA influences ...
