Biological Activity

Description Z-FA-FMK ((1S)-Z-FA-FMK) is an irreversible cysteine protease inhibitor, and also inhibits effector caspases.
Targets
cysteine protease [1]
In vitro

Z-FA-FMK inhibits the degradation of fibrillar collagen by fibroblasts and osteoclasts. [2] Z-FA-FMK inhibits LPS-induced cytokine production via inhibition of NF-kappaB-dependent gene expression in macrophages. [3] Z-FA-FMK efficiently blocks T cell proliferation induced by mitogens and IL-2 in vitro. [4]

In vivo Z-FA-FMK significantly increases pneumococcal growth in both lungs and blood in a mouse model of intranasal pneumococcal infection. [4] Z-FA-FMK blocks reovirus infection of Ras oncogenic tumours and host heart tissues in severe combined immunodeficiency mice. [5]

Protocol (from reference)

Cell Research:[4]
  • Cell lines: PBMCs
  • Concentrations: ~100 μM
  • Incubation Time: 72 hours
  • Method: T cell proliferation following mitogen stimulation is determined using [3H]thymidine incorporation. In brief, PBMCs or purified T cells are seeded in a 96-well plate and stimulated with either PHA (5 μg/ml), costimulated with anti-CD3 mAb (5 μg/ml) and anti-CD28 mAb (2.5 μg/ml) or PMA plus ionomycin in the presence or absence of z-FA-FMK. The cells are cultured for 72 h with the last 16 h pulsed with [methyl-3H]thymidine (0.037 MBq). The cells are harvested onto glass fiber filter mats using a Tomtec automated multiwell harvester.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
