Avis client

Based on 1 Customer Validation

Clonixin (SCH-10304) is an orally active non-steroidal anti-inflammatory agent (NSAID) that inhibits COX synthesis. Clonixin acts as a voltage-gated L-type calcium channel blocker, exerts vasodilatory effects by antagonizing Ca²⁺ in vascular smooth muscle. Clonixin inhibits TGF-β, reduces lung coefficient, immune cell infiltration level, oxidative stress response, airway resistance, hydroxyproline content and collagen deposition. Clonixin can be used in research related to inflammation such as idiopathic pulmonary fibrosis and moderate to severe pain.

In Vivo

Clonixin (142 mg/kg; p.o.; daily; 7 days) administered during either the inflammatory or fibrotic phase of Bleomycin (HY-108345)-induced pulmonary fibrosis in male Sprague Dawley rats significantly reduces lung fibrosis, oxidative stress, inflammation, and improves respiratory function, with marked reductions in hydroxyproline content and Ashcroft scores^[1].
Clonixin (40-120 mg/kg; i.p.; single dose) produces dose-dependent analgesia in the rat formalin nociception model^[3].
Clonixin (i.p.) has an intraperitoneal LD₅₀ of 308.0 mg/kg in Wistar rats^[3].
Clonixin (i.p.) has an intraperitoneal LD₅₀ of 266.4 mg/kg in Swiss AsW mice^[3].
Clonixin (Low-intermediate-high exposure doses; i.v.; single dose) produces dose-dependent hypotension and bradycardia in rats, with reversibility limited to low doses^[4].

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

Result:

Attenuated bleomycin-induced body weight loss.
Significantly reduced lung coefficient.
Significantly reduced airway resistance.
Markedly reduced total leukocyte count in bronchoalveolar lavage fluid (BALF).
Significantly reduced lymphocyte count in BALF.
Significantly reduced monocyte count in BALF.
Reduced lung tissue malondialdehyde (MDA) levels, and restored reduced glutathione (GSH), superoxide dismutase (SOD), and catalase levels.
Significantly reduced lung hydroxyproline content.
Significantly reduced Ashcroft fibrosis score.
Reduced immunohistochemical expression of fibrotic markers α-SMA, FAP, and TNF-α in lung tissue, particularly in the days 8-14 dosing group.

Animal Model:

Wistar (adult male and female; formalin-induced nociception model)^[3]
Dosage:

40 mg/kg; 80 mg/kg; 120 mg/kg
Administration:

i.p.; single dose
Result:

Had no effect on formalin-induced nociceptive response at 40 mg/kg.
Produced significant, dose-dependent reductions in pain intensity ratings at 80 mg/kg and 120 mg/kg.
Showed non-linear temporal course of analgesia at 120 mg/kg, with pain ratings returning to control levels by end of 30-minute observation period.
Significantly reduced formalin-induced pain intensity when combined with nifedipine 5 mg/kg at 80 mg/kg.
Was approximately 10 times less potent than nifedipine and morphine in this assay.

Stock Solution Working Solution

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 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (9.52 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
