Human adipose tissue-derived mesenchymal stem cells (hAMSCs)	1-100 µM	14 days	To investigate the effect of PG on adipogenic differentiation of hAMSCs. Results showed that PG significantly reduced lipid droplets accumulation and adipocyte differentiation in a dose-dependent manner.	Mol Cells. 2015 Apr;38(4):336-42
Human pulmonary fibroblast (HPF) cells	800–1600 µM	24 hours	PG increased the number of GSH-depleted cells and reduced GSH levels	Sci Rep. 2024 Mar 5;14(1):5375
A549 lung cancer cells	800 µM	24 hours	To evaluate the effect of propyl gallate on the proliferation and cell death of A549 lung cancer cells. Results showed that 800 μM propyl gallate inhibited proliferation and induced cell death in A549 cells at 24 hours.	Molecules. 2022 Jul 18;27(14):4587
Calu-6 lung cancer cells	800 µM	24 hours	To evaluate the effect of propyl gallate on the proliferation and cell death of Calu-6 lung cancer cells. Results showed that 800 μM propyl gallate inhibited proliferation and induced cell death in Calu-6 cells at 24 hours.	Molecules. 2022 Jul 18;27(14):4587
Human pulmonary fibroblast (hPF) cells	100–1,600 µM	24 hours	PG significantly impacted the cell cycle, leading to G1 phase arrest, and slightly increased the number of sub-G1 cells at 1,600 μM. Additionally, PG (400–1,600 μM) initiated cell death, coinciding with a loss of mitochondrial membrane potential (MMP; ΔΨm).	Ann Med. 2024 Dec;56(1):2319853
Human pulmonary fibroblast (HPF) cells	100–800 µM	30–180 min and 24 hours	PG increased levels of total ROS and O2·−, leading to cell death	Sci Rep. 2024 Mar 5;14(1):5375

HA cells	50 µM or 100 µM	48 hours	Evaluate the cytotoxicity of PG on normal HA cells. 50 or 100 μM PG did not induce cytotoxicity.	J Immunol Res. 2017;2017:9489383
HBVP cells	50 µM or 100 µM	48 hours	Evaluate the cytotoxicity of PG on normal HBVP cells. 50 or 100 μM PG did not induce cytotoxicity.	J Immunol Res. 2017;2017:9489383
U87MG cells	50 µM or 100 µM	48 hours	Evaluate the inhibitory effect of PG alone or in combination with TMZ on the migration of U87MG cells. PG (100 μM) alone significantly inhibited migration, and the inhibitory effect was further enhanced when combined with TMZ.	J Immunol Res. 2017;2017:9489383

Veal calves, cattle for fattening, dairy cows, sheep, goats, sows, horses and salmonids	Various animal models	Feed additive	40 mg/kg (food-producing animals), 100 mg/kg (non-food-producing animals)	Continuous use	To evaluate the safety of propyl gallate as a feed additive, results showed safety for various animal species at the proposed maximum use levels.

Cats	Healthy cats	Oral	71, 355, 710 mg/kg feed	Twice daily for 28 days	To evaluate the safety of propyl gallate in cats. Results showed no adverse effects were observed during the 28-day dietary exposure, including hematology and serum biochemistry parameters.	EFSA J. 2024 Feb 29;22(2):e8638
