| Description | Methacycline hydrochloride (Rondomycin) is a broad-spectrum semisynthetic antibiotic related to TETRACYCLINE but excreted more slowly and maintaining effective blood levels for a more extended period. |
| In vitro | Methacycline, within pulmonary alveolar macrophages, does not alter the response gene of TGF-β1 nor attenuates the aggregation of inflammatory cells. Following tracheal aspiration of bleomycin, intraperitoneal injection of Methacycline at 100 mg/kg, starting on day 10, enhances survival rates by day 17. Methacycline mitigates bleomycin-induced classical EMT (Epithelial-Mesenchymal Transition) markers, including SNAIL1, TWIST1, type I collagen, fibronectin, and their mRNA expressions. |
| In vivo | Methacycline inhibits the TGF-β1-induced non-Smad signaling pathways, including the activation of c-Jun N-terminal kinase (JNK), p38, and Akt, without suppressing Smad or β-catenin transcriptional activities. It does not affect the baseline activities of JNK, p38, or Akt, nor the TGF-β1 response of lung fibroblasts. Additionally, methacycline inhibits the TGF-β1-induced expression of α-smooth muscle actin (α-SMA), SNAIL1, and type I collagen in primary alveolar epithelial cells. |

DMSO
| |||||||||||||||||||||||||||||||
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.
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.
