Description

LHVS is a potent, non-selective, irreversible, cell-permeable cysteine protease and cathepsin inhibitor. LHVS decreases actin ring formation. LHVS inhibits T. gondii invasion with an IC50 of 10 μM[1][2][3].

IC50 & Target

cathepsin K

 

cathepsin L

 

Cathepsin B

 

In Vitro

LHVS (5 μM, 2 h) results in a 50% reduction of actin ring formation in wild-type osteoclasts when compared with untreated osteoclasts[1].
LHVS acts in a dose-dependent manner on osteoclasts and at 5 μM, LHVS inhibits cathepsins K, L, S, and B[1].
LHVS (1-5 nM) can inhibit specifically cathepsin S in HOM2 cells, leaving other cysteine proteases functionally active[3].
LHVS impairs tachyzoite attachment by blocking the release of at least two key invasion proteins, MIC2 and M2AP, from the micronemes[2].
LHVS (50 μM) selectively impairs microneme protein secretion[2].

In Vivo

LHVS (3-30 mg/kg, SC, once) shows anti-hyperalgesic effect in neuropathic rats[4].
LHVS (30 nmol per rat, spinal delivery, daily) is antinociceptive in neuropathic rats[5].
LHVS (1-50 nmol per rat, Intrathecal injection, daily) reverses established neuropathic mechanical hyperalgesia in 14-day neuropathic rats[5].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Wistar rats (180-220 g)[4]
Dosage: 3-30 mg/kg
Administration: SC, once
Result: Produced a dose-dependent reversal of the mechanical hyperalgesia which lasted up to 3 h in neuropathic rats. In contrast, a single systemic administration of LHVS did not reverse mechanical allodynia in neuropathic rats.
Animal Model: Male Wistar rats received a partial ligation of the left sciatic nerve (PNL)[5]
Dosage: 30 nmol per rat
Administration: Spinal delivery, Daily
Result: Failed to prevent the development of allodynia when continuous delivery from day 0 to day 7 post-PNL, but significantly reversed allodynia on day 7 post-PNL. In addition, the delivery of LHVS from day 7 to day 14 post-PNL significantly reversed established mechanical allodynia from day 8.
Animal Model: Male Wistar rats received a partial ligation of the left sciatic nerve (PNL)[5]
Dosage: 1, 10 or 50 nmol per rat
Administration: Intrathecal injection, Daily
Result: Reduced established mechanical hyperalgesia. This effect was dose-dependent and remained significant until 3 h after administration of the highest dose.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (4.74 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 2.5 mg/mL (4.74 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
