Pipecolic acid
Based on 2 publication(s) in Google Scholar
Pipecolic acid is an orally bioavailable, blood-brain barrier-permeable metabolite of lysine with antioxidant, inhibitor, and inducer activity. Pipecolic acid modulates the YAP-GPX4 signaling pathway, reduces retinal vascular tube formation, and mitigates ferroptosis. Pipecolic acid potentiates voltage-sensitive Ca2+ channel currents and induces neuronal apoptosis. Pipecolic acid can be used for the research of diabetic retinopathy.

Pipecolic acid mitigates high-glucose-induced oxidative stress, cell growth inhibition, and apoptosis, and downregulates YAP and GPX4 expression in human retinal capillary endothelial cells[1].
DL-pipecolic acid (1, 10, 100 μM; 20 min) potentiates population spike amplitude in the dentate gyrus of rat hippocampal slices at 10 and 100 μM, while D- and L-pipecolic acid show no significant inhibitory effect[2].
DL-pipecolic acid (10, 100 μM) does not significantly affect voltage-sensitive Na+ channel and voltage-sensitive K+ channel currents in Neuro-2A cells at 10 or 100 μM[2]. DL-pipecolic acid
DL-pipecolic acid (10, 100 μM) potentiates voltage-sensitive Ca2+ channel currents in cultured rat cortical neurons at 10 and 100 μM[2].
DL-pipecolic acid (1, 10, 100 μM; 72 h) reduces viability of Neuro-2A cells in a dose-dependent manner, with the most potent effect among D-, L-, and DL-enantiomers[2].
DL-pipecolic acid (100 μM; 72 h) induces cell death and apoptosis in Neuro-2A cells, as indicated by propidium iodide and Hoechst 33342 staining[2].

Cell Line:Neuro-2A cells (mouse neuroblastoma cell line)
-
Concentration:1, 10, 100 μM
-
Incubation Time:72 h
-
Result:Reduced cell viability in a dose-dependent manner to 68 ± 4% (1 μM), 60 ± 6% (10 μM), and 48 ± 4% of control levels (100 μM); exhibited the most potent effect among D-, L-, and DL-enantiomers.
Pipecolic acid (250 mg/kg; i.g.; daily; 14 days) improves body weight gain and reduces retinal pathological changes in YAP knockout mice with streptozotocin-induced diabetic retinopathy, though its efficacy is diminished relative to its effects in wild-type mice[1].

Animal Model:C57BL/6 (male, 8 weeks old, ~25 g, streptozotocin-induced type 1 diabetes)[1]
-
Dosage:250 mg/kg
-
Administration:i.g.; daily; 7 days
-
Result:Achieved significantly higher body weight gain (11.04 ± 1.85 g) compared to untreated diabetic mice; reduced serum glucose levels; significantly decreased the ratio of retinal positive areas to whole positive areas; reversed diabetic-induced oxidative stress changes by reducing retinal malondialdehyde, reactive oxygen species, and iron content, while increasing retinal glutathione peroxidase, catalase, and superoxide dismutase levels; significantly increased retinal YAP mRNA expression compared to untreated diabetic mice; reduced the ratio of endothelial cells to pericytes, the number of acellular capillaries, and the level of mitophagy autosomes/nucleus in retinal tissue compared to untreated diabetic mice.

-
Dosage:250 mg/kg

Administration:i.g.; daily; 14 days

Result:Achieved significantly higher body weight gain compared to untreated YAP knockout diabetic mice; did not significantly affect blood glucose levels; reduced the ratio of retinal positive areas to whole positive areas, the ratio of endothelial cells to pericytes, the number of acellular capillaries, and the ratio of epithelial cells to retinal pericytes compared to untreated YAP knockout diabetic mice; significantly reduced retinal GPX4 and VEGF protein expression compared to untreated YAP knockout diabetic mice.
