Radezolid (INN, codenamed RX-1741) is a novel oxazolidinone antibiotic being developed by Melinta Therapeutics, Inc. for the treatment of bacterial acne. [1]
Linezolid is an antibiotic used for the treatment of infections caused by Gram-positive bacteria that are resistant to other antibiotics. Linezolid is active against most Gram-positive bacteria that cause disease, including streptococci, vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA). The main uses are infections of the skin and pneumonia although it may be used for a variety of other infections including drug-resistant tuberculosis. It is used either by injection into a vein or by mouth.
Levofloxacin, sold under the brand name Levaquin among others, is an antibiotic medication. It is used to treat a number of bacterial infections including acute bacterial sinusitis, pneumonia, H. pylori, urinary tract infections, chronic prostatitis, and some types of gastroenteritis. Along with other antibiotics it may be used to treat tuberculosis, meningitis, or pelvic inflammatory disease. Use is generally recommended only when other options are not available. It is available by mouth, intravenously, and in eye drop form.
Clindamycin is an antibiotic medication used for the treatment of a number of bacterial infections, including osteomyelitis (bone) or joint infections, pelvic inflammatory disease, strep throat, pneumonia, acute otitis media, and endocarditis. It can also be used to treat acne, and some cases of methicillin-resistant Staphylococcus aureus (MRSA). In combination with quinine, it can be used to treat malaria. It is available by mouth, by injection into a vein, and as a cream or a gel to be applied to the skin or in the vagina.
Anidulafungin (INN) is a semisynthetic echinocandin used as an antifungal drug. It was previously known as LY303366. It may also have application in treating invasive Aspergillus infection when used in combination with voriconazole. It is a member of the class of antifungal drugs known as the echinocandins; its mechanism of action is by inhibition of (1→3)-β-D-glucan synthase, an enzyme important to the synthesis of the fungal cell wall.
Temocillin is a β-lactamase-resistant penicillin introduced by Beecham, marketed by Eumedica Pharmaceuticals as Negaban. It is used primarily for the treatment of multiple drug-resistant, Gram-negative bacteria.
It is a 6-methoxy penicillin; it is also a carboxypenicillin.
Enoxacin is an oral broad-spectrum fluoroquinolone antibacterial agent used in the treatment of urinary tract infections and gonorrhea. Insomnia is a common adverse effect. It is no longer available in the United States.
Retapamulin is a topical antibiotic developed by GlaxoSmithKline. It is the first drug in the new class of pleuromutilin antibiotics to be approved for human use. It is marketed as an ointment under the brand names Altabax and Altargo.
Temafloxacin is a fluoroquinolone antibiotic drug which was withdrawn from sale in the United States shortly after its approval in 1992 because of serious adverse effects resulting in three deaths. It is not marketed in Europe.
Nitroxoline is an antibiotic that has been in use in Europe for about fifty years, and has proven to be very effective at combating biofilm infections. Nitroxoline was shown to cause a decrease in the biofilm density of P. aeruginosa infections, which would allow access to the infection by the immune system in vivo. It was shown that nitroxoline functions by chelating Fe2+ and Zn2+ ions from the biofilm matrix; when Fe2+ and Zn2+ were reintroduced into the system, biofilm formation was reconstituted. The activity of biofilm degradation is comparable to EDTA, but has a history of human use in clinical settings and therefore has a precedent with which to allow its use against “slimy” biofilm infections.
Aminocoumarin is a class of antibiotics that act by an inhibition of the DNA gyrase enzyme involved in the cell division in bacteria. They are derived from Streptomyces species, whose best-known representative – Streptomyces coelicolor – was completely sequenced in 2002. The aminocoumarin antibiotics include:
A protein synthesis inhibitor is a compound that stops or slows the growth or proliferation of cells by disrupting the processes that lead directly to the generation of new proteins.
Mecillinam (INN) or amdinocillin (USAN) is an extended-spectrum penicillin antibiotic of the amidinopenicillin class that binds specifically to penicillin binding protein 2 (PBP2), and is only considered to be active against Gram-negative bacteria. It is used primarily in the treatment of urinary tract infections, and has also been used to treat typhoid and paratyphoid fever. Because mecillinam has very low oral bioavailability, an orally active prodrug was developed: pivmecillinam.
Ciclacillin (INN) or cyclacillin (USAN), trade names Cyclapen, Cyclapen-W, Vastcillin, and others, is an aminopenicillin antibiotic. Its spectrum of activity is similar to that of ampicillin, although it is less susceptible to beta-lactamases than ampicillin and has much higher bioavailability. A large randomized, double-blind clinical trial published in 1978 also showed that ciclacillin is associated with significantly fewer and milder adverse effects than ampicillin; later studies seemed to confirm this improved tolerability, at least in children.
Alisporivir (INN), or Debio 025, DEB025, is a cyclophilin inhibitor. Its structure is reminiscent of, and synthesized from ciclosporin.
Ceftaroline fosamil (INN), brand name Teflaro in the US and Zinforo in Europe, is a cephalosporin antibiotic with anti-MRSA activity. Ceftaroline fosamil is a prodrug of ceftaroline. It is active against methicillin-resistant Staphylococcus aureus (MRSA) and other Gram-positive bacteria. It retains some activity of later-generation cephalosporins having broad-spectrum activity against Gram-negative bacteria, but its effectiveness is relatively much weaker. It is currently being investigated for community-acquired pneumonia and complicated skin and skin structure infection.
Nemonoxacin is a non-fluorinated quinolone antibiotic undergoing clinical trials. It has the same mechanism of action as fluouroquinolones; it inhibits DNA gyrase, preventing DNA synthesis, gene duplication, and cell division. At the end of 2016, it had reached market in Taiwan, Russia, the Commonwealth Independent States, Turkey, mainland China, and Latin America under the brand name Taigexyn. Nemonoxacin has completed phase 2 trials in the US and has moved on to phase 3 trials. The U.S. Food and Drug Administration (FDA) has granted nemonoxacin qualified infectious disease product (QIDP) and fast track designations for community-acquired bacterial pneumonia (CAP) and acute bacterial skin and skin-structure infections (ABSSSI).
OSU-03012 (AR-12) is a celecoxib derivative with anticancer and anti-microbial activity. Unlike celecoxib, OSU-03012 does not inhibit COX, but inhibits several other important enzymes instead which may be useful in the treatment of some forms of cancer, When combined with PDE5 inhibitors such as sildenafil or tadalafil, OSU-03012 was found to show enhanced anti-tumour effects in cell culture.
Karen Bush is an American biochemist. She is a Professor of Practice in Biology at Indiana University and the interim director of the Biotechnology program. Bush conducts research focusing on bacterial resistance mechanisms to beta-lactam antibiotics.
Karen Joy Shaw is an American microbiologist and discoverer of novel antifungal and antibacterial compounds. She is best known for her work on aminoglycoside resistance in bacteria as well as leading drug discovery research teams. As Senior Vice President of Biology at Trius Therapeutics, Inc. her work was critical to the development of the oxazolidinone antibiotic tedizolid phosphate (Sivextro) as well as the discovery of the TriBE inhibitors, a novel class of DNA gyrase/Topoisomerase IV antibacterial agents that target both Gram-positive and Gram-negative organisms.[2] As Chief Scientific Officer at Amplyx Pharmaceuticals, Shaw was responsible for the preclinical development of the novel antifungal fosmanogepix, a first-in-class broad-spectrum antifungal prodrug that is currently in Phase 2 clinical development for the treatment of invasive fungal infections. She also discovered APX2039, a unique Gwt1 inhibitor that is in preclinical development for the treatment of cryptococcal meningitis.
Lascufloxacin is an fluoroquinolone antibiotic drug for the treatment of bacterial infections. It has been approved since 2019 in Japan to treat community-acquired pneumonia, otorhinolaryngological infections, and respiratory tract infections.
