Samuelin™ is a second-generation pleuromutilin semi-synthetic antibiotic, which is a special antibiotic for diterpene
animals. Berner et al. obtained it by modifying the chemical structure of pleuromutilin in 1984. It was approved by the
European Community in 1999 for the prevention and treatment of swine dysentery caused by B. hyodysenteriae infection
and swine endemic pneumonia caused by Mycoplasma pneumoniae infection.
Vonimulin hydrochloride is a white or light yellow crystalline powder, hygroscopic, soluble in water and absolute ethanol,
insoluble in tert-butyl methyl ether, and has a pH of 3.0-6.0.
Vonimulin is the first veterinary drug premix approved in Europe and is listed as a veterinary prescription drug. Vonimulin has
strong antibacterial activity, which is derived from its unique antibacterial mechanism, that is, it inhibits
the protein synthesis of pathogenic microorganisms by binding to the site of pathogenic microorganism ribosomal 23SrRNA, leading
to the death of pathogenic microorganisms. In January 2004, the European Union approved the prevention of porcine colic spirochetosis
(colitis) caused by colonic piliformis infection and the treatment of porcine proliferative enteropathy (ileitis) caused by Lawsonia intracellularis
infection. B. hyodysenteriae, B. pilaris and Lawsonia intracellularis are the culprits of most growing swine enteritis. In 2010, the European Union
again approved the increase of epidemic enteritis in rabbits.
Vonimulin has broad antibacterial properties and is effective against Gram-positive bacteria, negative bacteria, Mycoplasma
and Spirochetes, but it is less effective against intestinal bacteria (such as Escherichia coli and Salmonella). It has good antibacterial
activity against Staphylococcus aureus, Streptococcus pneumoniae, Mycoplasma bovis, Mycoplasma gallisepticum, Mycoplasma
hyopneumoniae, Mycoplasma hyopneumoniae, Mycoplasma hyodysenteriae, B. hyodysenteriae, B. coliformis, Lawsonia intracellularis,
etc. , Especially highly sensitive to Mycoplasma, Spirochetes and Rousella intracellularis. At present, it is often used clinically to prevent
swine dysentery, swine diarrhea and swine endemic pneumonia. It can also be used for mycoplasma bovine disease, hoof disease and
mycoplasma infection in chickens, dogs, and cats. In addition, Vonimulin is more active against Helicobacter pylori than metronidazole
and tetracycline, and its activity against Mycobacterium tuberculosis is better than traditional anti-tuberculosis drugs such as isoniazid,
rifampicin and streptomycin, so it is occasionally used. For human drug-resistant Mycoplasma infection and so on.
Special process, microcapsule coating. Unique anti-moisture and anti-degradation technology, higher drug stability, and can play
a slow-release effect, improve drug efficacy.
Broad antibacterial spectrum and strong antibacterial activity. It has good antibacterial activity against Mycoplasma of livestock and
poultry, Treponema hyodysenteriae, Treponema piliformis, Lawsonia intracellularis, etc. Experiments show that its anti-mycoplasma activity
is 5-10 times that of tiamulin. It has been recognized by the industry as the drug of choice for the treatment of Mycoplasma in livestock and
poultry.
High bioavailability and rapid oral absorption. EMEA (European Medical Products Evaluation Center) reported that the bioavailability
of the product is close to 100%.
The tissues are widely distributed and targeted. Tests have shown that Vonemulin highly accumulates in lung tissues and intestines,
and the intracellular drug concentration is much greater than extracellular.
High efficiency and low residue. The drug withdrawal period is only 1 day.
No drug resistance. Unique structure, no cross-resistance with other drugs.
Very low toxicity. No reproductive toxicity, no teratogenicity, mutagenicity and carcinogenicity, no effect on the immune system.

vornemulin on Mycoplasma gallisepticum that were artificially inoculated with 105, 106 and 107 CFU/mL, The MIC value of Vonemulin to
Mycoplasma is extremely low.
Vonimulin is very sensitive to Mycoplasma suis

Description: Vonimulin can effectively prevent and control swine dysentery, swine colitis and swine ileitis three major intestinal diseases.
(4) Highly effective anti-inflammatory, preventing the occurrence of "inflammatory storm"
Inflammation is a concurrent disease caused by other diseases, which seriously affects the health of humans and animals, and even
threatens lives (most patients with new coronaviruses stop breathing due to the "inflammatory storm"). Including acute respiratory distress
syndrome, systemic inflammatory response syndrome, sepsis, multiple organ dysfunction syndrome, etc. Chen Zhibao and others found that
Vonimulin can prevent the transfer of P65 in the cytoplasm to the inside of macrophages, thereby preventing the occurrence of "inflammatory storm".
Conclusion: In the control group, without LPS stimulation, P65 is present in the cytoplasm. After 30 minutes of LPS stimulation, P65
concentrated into the nucleus, inducing an "inflammatory storm". In the test group, vornemulin-treated cells inhibited P65 metastasis
in the cytoplasm in a dose-dependent manner, thereby inhibiting the occurrence of inflammation.
Explanation: LPS is the main component (endotoxin) of Gram-negative bacteria and is the direct cause of inflammation.
P65 is a kind of nuclear transcription factor (NF-kB), which is closely related to inflammation.
DAPI is 4',6-diamidino-2-phenylindole, which can bind to DNA or RNA and emit blue fluorescence under a fluorescence microscope.
