Torezolid Chemical Properties,Uses,Production
Novel antibacterial drugs
Tedizolid belongs to the second generation oxazolidinone antibiotics, being an analog of linezolid as well as a kind of protein synthesis inhibitors, acting on the bacterial ribosomal 50S subunit and causing inhibition of bacterial protein synthesis. Compared with linezolid, the efficacy of the two is basically the same, but linezolid required to be taken for 2 times a day and for 10 continuous days while Tedizolid only takes 1 time daily and continuous taking for 6 days.
On June 20, 2014, the US FDA had approved a new antimicrobial drug Tedizolid (trade name: Sivextro) for the treatment of skin infections in adult patients. Sivextro is approved for the treatment of acute bacterial skin and skin infections caused by certain sensitive bacteria such as Staphylococcus aureus (including methicillin-resistant strains and methicillin-sensitive strains), various streptococci and Enterococcus faecalis (ABSSSI). Sivextro is administered intravenously and orally.
Tedizolid phosphate is a second-generation oxazolidinone antibiotic developed by Dong-A Pharmaceutical, licensed to Cubist Pharmaceuticals and Bayer for commercial development.
Sivextro is designed for the treatment of serious or life-threatening infections, and its listing applications are eligible for Qualified Infectious Disease Products (QIDP) and have obtained the approve of FDA for accelerated review. Sivextro's QIDP eligibility gives the drug exclusive five-year market exclusivity, in addition to its market exclusivity under the Food, Drug, and Cosmetic Act.
The safety and efficacy of Sivextro were evaluated in two clinical trials involving 1315 ABSSSI adult patients. Subjects were randomized to Sivextro or another antibiotic linezolid approved for the treatment of acute bacterial skin and skin structure infections (ABSSSI). The results showed that its clinical efficacy is equivalent to linezolid. However, it will cause less gastrointestinal adverse reactions and thrombocytopenia adverse reactions than linezolid. The incidence of drug resistance is also lower. Tedizolid has been shown to be more tolerant than vancomycin.
The most common side effects identified in clinical trials include nausea, headache, diarrhea, vomiting and dizziness. The safety and efficacy of Sivextro have not been evaluated in patients with reduced white blood cell levels (neutropenia), so alternative therapies should be considered for these patients. Sivextro is marketed by Cubist Pharmaceuticals, Inc., based in Lexington, Massachusetts.
Status of intellectual property: Compound patent ZL200480037612.2, protection period 2024.12.17 expires.
This information was edited by Xiao Nan from Chemicalbook (2015-08-14).
Indications
Tedizolid phosphate is an oxazolidinone compound used in the treatment of acute bacterial skin and skin structure infections caused by the following gram-positive bacteria-sensitive strains: Staphylococcus aureus (including Methicillin-resistant and methicillin-susceptible strains), pyogenic streptococci, Streptococcus lactis, Streptococcus angustifolia (including Angina, Streptococcus intermedius and Streptococcus constellation), and Enterococcus faecalis.
State of Intellectual Property
(A) Administrative protection, new drug protection and new drug monitoring period
On August 9, 2013, Bayer Pharmaceuticals has filed a new drug application with CFDA.

Uses
Tedizolid, known as TR-700, is an oral and i.v administered intracellular antibacterial drug.
Definition
ChEBI: A member of the class of pyridines that is pyridine which is substituted by a 2-methyl-2H-tetrazol-5-yl group at position 2 and by a 2-fluoro-4-[(5R)-5-(hydroxymethyl)-2-oxo-1,3-oxazolidin-3-yl]phenyl group at position 5 It is used as its phosphate pro-drug used for the treatment of acute bacterial skin and skin structure infections caused by certain susceptible bacteria, including Staphylococcus aureus (including methicillin-resistant strains (MRSA) and meth cillin-susceptible strains), various Streptococcus species, and Enterococcus faecalis.
Biological Activity
tedizolid is an oxazolidinone antimicrobial agent with mic50 value of 0.5 μg/ml for mssa, mrsa, vr e. faecium and vr e. faecalis and 0.25 μg/ml for msse, mrse, pssp and prsp [1].the resistant gram-positive infection is a serious global health problem. for instant, the methicillin-resistant s. aureus (mrsa) has spread all over the world with rates ranging from 18 to 26 cases among 100,000 people. besides that, there come out a serious of resistant strains such as the linezolid-resistant s. aureus (lrsa) and the vancomycin-resistant s. aureus (vrsa). due to the unfavorable outcomes of the existed antibiotics, alternative treatments have been developed. tedizolid is a synthetic antibiotic that works based on the inhibition of protein synthesis. it binds to the 50s ribosome and inhibits the formation of the 70s complex [1].tedizolid showed potent bacteriostatic activity against many resistant gram-positive pathogens such as mssa, mrsa, s. pyogenes and s. pneumoniae. for the enterococcal and staphylococcal isolates, tedizolid displayed more than 4-fold higher potency than that of linezolid. it also showed inhibitory effects on a panel of 169 linezolid-resistant staphylococcal isolates with 79.2% inhibition at concentration of ≤ 4μg/ml. the mic values of tedizolid against linezolid-resistant staphylococci were in a range from 0.06 to 16 mg/l. besides that, tedizolid was found to be the inhibitors of human monoamine oxidase with ic50 values of 8.7 and 5.7 μm for mao-a and mao-b, respectively [1, 2 and 3].when treated in vivo, tedizolid was the active moiety converted from the pro-drug tedizolid phosphate. it was found that granulocytes could affect the antistaphylococcal effect of tedizolid. in neutropenic mice, the administration of tedizolid for 24 hours or 48 hours caused ed50 values of 25.2 and 35.7 mg/kg/day, respectively [1 and 4].
