| Targets |
Sancycline HCl targets the 30S ribosomal subunit in bacteria. As a tetracycline-class antimicrobial agent, it inhibits protein synthesis within susceptible bacteria by binding reversibly to the 30S ribosomal subunit, preventing the binding of aminoacyl-tRNA to the ribosome A site. The compound has broad-spectrum activity against various Gram-positive and Gram-negative bacteria. It is active against tetracycline-resistant E. coli strains.

In vitro release of pure Sancycline HCl from suspension: in PBS (pH 7.4 and pH 5.6, both with 0.5% Tween 80), approximately 95% of the drug was released within 10 hours, showing a burst release profile. [1]
Cytotoxicity of pure Sancycline HCl against HeLa cells: at 20 µM for 24 h, cell viability was 70.9 ± 7.5%; at 20 µM for 48 h, cell viability was 61.1 ± 4.4%. [1] Morphological changes: HeLa cells treated with 20 µM Sancycline HCl for 6 h showed no obvious effect on cell morphology. [1] In vitro, Sancycline HCl is more active than tetracycline against 339 strains of anaerobic bacteria with average MIC90s of 1 μg/ml compared to 32 μg/ml for tetracycline. It is a broad-spectrum tetracycline-class antibiotic known for its exceptional potency against various Gram-positive and Gram-negative bacteria. The compound is active against tetracycline-resistant E. coli. Its antibacterial activity has been characterized against a wide range of bacterial pathogens. |

MTT assay for cytotoxicity: HeLa cells were plated in 96-well plates at 8×10³ cells per well. After 12 h, cells were exposed to various concentrations of Sancycline HCl (including 20 µM) for 24 or 48 h. MTT solution was added to a final concentration of 0.5 mg/mL and incubated for 4 h at 37°C.

In vitro release assay: Freshly prepared Sancycline HCl suspension (5 mL; 100 µg/mL) was placed into a pre-swelled dialysis bag (7 kDa MW cutoff). The bag was incubated in release medium (PBS pH 7.4 or pH 5.5, 20 mL with 0.5% Tween 80) at 37°C under horizontal shaking. At predetermined time points, the bag was transferred to fresh medium. Released CMT-3 content was determined by HPLC (mobile phase MeOH:H₂O with 0.5% TFA = 30:70, flow rate 1 mL/min, wavelength 360 nm).

| Additional Infomation |
Sancycline HCl (CMT-3) is a 4-demethylaminosancycline derivative of tetracycline. It lacks antimicrobial activity but inhibits matrix metalloproteinases (MMPs). It has shown anti-tumor and anti-metastatic effects in various cancer models (e.g., breast, colon, prostate, melanoma). However, its poor water solubility limits clinical use as a parenteral drug. Adverse effects observed in clinical trials (referenced from other studies) include nausea, vomiting, liver function abnormalities, diarrhea, mucositis, leukopenia, and thrombocytopenia. [1]
Sancycline HCl is a rare semi-synthetic tetracycline antibiotic more active than tetracycline against anaerobic bacteria (MIC90: 1 vs 32 μg/ml). It binds to the 30S ribosomal subunit and is active against tetracycline-resistant E. coli. It has a molecular weight of 450.87 g/mol and formula C21H23ClN2O7. The CAS number is 6625-20-3. |
