Levobupivacaine

Levobupivacaine ((S)-(-)-Bupivacaine) is a long-acting amide local agent that can suppress or relieve pain. Levobupivacaine exerts agent that can suppress or relieve pain. and analgesic effects through reversible blockade of neuronal sodium channel. Levobupivacaine can inhibit impulse transmission and conduction in cardiovascular and other tissues, possessing certain cardiac and CNS toxicity. Levobupivacaine is metabolized by hepatic cytochrome P450 (CYP450) enzymes in vivo. Levobupivacaine can also induce ferroptosis by miR-489-3p/SLC7A11 signaling in gastric cancer^[1][2][3]. IC50 & Target: Sodium channels, Ferroptosis^[1][2] In Vitro: Levobupivacaine (0-4 mM; 24 h) does not affect the viability of GES-1 cells but inhibits the viability of HGC27 and SGC7901 cells^[2].
Levobupivacaine (2 mM; 24, 48 or 72 h) enhances Erastin-induced inhibitory impact on HGC27 and SGC7901 cell viabilities; induces the levels of Fe²⁺, iron, and lipid ROS^[2].
Levobupivacaine (2 mM; 24 h) enhances the expression of miR-489-3p in HGC27 and SGC7901 cells, increases the levels of Fe²⁺ and iron^[2]. In Vivo: Levobupivacaine (40 μmol/kg; IP; once daily for 25 days) significantly inhibits SGC7901 cell growth, and enhances the lipid ROS accumulation^[2].
Levobupivacaine (5 or 36 mg/kg; IP; single dosage) increases the latency to partial seizures and prevents the occurrence of generalized seizures at low dosage; reduces the latency to N-methyl-d-aspartate (NMDA)-induced seizures and increased seizure severity at high dosage^[3].
