Product Introduction

Lactic acid AI Summary

Lactic acid shows notable bioactivities, including cytotoxic effects on cancer cells with p53 mutations at a potency of 25.1 nM. It also demonstrates the ability to block Ebola virus entry, with potency levels ranging from 35.48 µM to 39.81 µM in one assay and from 35481.3 nM to 39810.7 nM in another. Additionally, when administered topically at concentrations of 2% and 4% over four weeks, Lactic acid increases ceramide content in human skin. A similar increase is observed in keratinocytes at a concentration of 20 mM after 24 hours, with fold changes ranging from 1.4 to 4.3. It also exhibits cytotoxicity against human MRC5 cells (IC50 of 23,930,000 nM) and A549 cells (IC50 of 26,610,000 nM), determined by the MTT assay after 48 hours..

Bioactivity

Description	Lactic acid (2-hydroxypropanoic acid), a glycolysis end product, is a hydroxycarboxylic acid receptor 1 (HCAR1) activator (EC50=4.2-5 mM). Lactic acid can be used as a hemodynamic index in critically ill patients and has anti-tumor activity.
Targets & IC50	GPR109A:1 mM (EC50), GPR81 (HCAR1):1 mM (EC50), GPR109B:1 mM (EC50)
In vitro	METHODS: : Effects on cell proliferation and migration of uveal melanoma after treatment with Lactic acid (20 mM) for 24 and 48 hours. RESULTS: Lactic acid led to a significant reduction in cell proliferation and migration. [1] Method: Uveal melanoma was treated with Lactic acid (20 mM) for 24 hours, and the protein expression level was detected by western blot. Result: Lactic acid promoted the increase in the protein expression levels of MCT1 and HCAR1. [1]
In vivo	METHODS: To detect the anti-tumor activity in vivo, Lactic acid (1.6 g/kg) was subcutaneously injected into Female C57BL/6 mice with MC38 colon cancer cells; pH 7.4 Once a day; From Day 8 to Day 30. RESULTS: Lactic acid demonstrated CD8+ T cell-dependent tumor growth inhibition in the MC38 colon cancer model. [2]

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 µL Tween 80 and mix well until fully clarified.

3) Add 450 µL Saline,PBS or ddH₂O and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
