Biological Activity
SQDG is an acidic lipid that can be found in the thylakoid membrane of photosynthetic organisms such as plants and cyanobacteria. SQDG is the composition of the thylakoid membrane, provides a stable environment for membrane proteins and maintains the integrity of the membrane[2].
SQDG binds to four sites of photosystem II (PSII) and affects PSII activity. SQDG regulates the efficiency of photosynthesis. SQDG loss leads to growth inhibition in some cyanobacteria[2].
SQDG inhibits herpes simplex virus type 2 (HSV-1), HSV-2 (IC50=15.6 μg/mL) and Coxsackie virus B3 (Cox B3)[3].
SQDG (0-25 μM, 72 h) exhibits cytotoxicity in acute lymphoblastic leukemia (ALL) cells, IC50s for MOLT-4, MOLT-3 and Reh are 15.32 μM, 22.52 μM and 19.63 μM[4].
SQDG (0-25 μM, 24-48 h) arrests the cell cycle at S phase, and induces apoptosis in MOLT-4 through p53-dependent pathway[4].
