2. Urinary anti-infective agent - Wikipedia

   en.wikipedia.org/wiki/Urinary_anti-infective_agent

   TMP/SMX is commonly used due to its ability to achieve high concentrations in urinary tract tissues and urine. This antibiotic combination demonstrates notable efficacy in both the treatment and prophylaxis of recurrent urinary tract infections. [12] Common adverse effects include nausea, vomiting, rash,pruritus, and photosensitivity. [26]

3. Oseltamivir - Wikipedia

   en.wikipedia.org/wiki/Oseltamivir

   Oseltamivir was discovered by scientists at Gilead Sciences using shikimic acid as a starting point for synthesis; shikimic acid was originally available only as an extract of Chinese star anise; but by 2006, 30% of the supply was manufactured recombinantly in E. coli. [65] [66] Gilead exclusively licensed their relevant patents to Roche in ...

   en.wikipedia.org/wiki/Treatment_of_influenza

   Treatments for influenza include a range of medications and therapies that are used in response to disease influenza.Treatments may either directly target the influenza virus itself; or instead they may just offer relief to symptoms of the disease, while the body's own immune system works to recover from infection.

5. Oseltamivir total synthesis - Wikipedia

   en.wikipedia.org/wiki/Oseltamivir_total_synthesis

   The current production method is based on the first scalable synthesis developed by Gilead Sciences [4] starting from naturally occurring quinic acid or shikimic acid.Due to lower yields and the extra steps required (because of the additional dehydration), the quinic acid route was dropped in favour of the one based on shikimic acid, which received further improvements by Hoffmann-La Roche.

6. Probenecid - Wikipedia

   en.wikipedia.org/wiki/Probenecid

   Probenicid lowers the concentration of certain drugs in urine drug screens by reducing renal excretion of these drugs. Historically, probenecid has been used to increase the duration of action of drugs such as penicillin and other beta-lactam antibiotics. Penicillins are excreted in the urine at proximal and distal convoluted tubules through ...

7. Shikimic acid - Wikipedia

   en.wikipedia.org/wiki/Shikimic_acid

   Shikimic acid can also be extracted from the seeds of the sweetgum (Liquidambar styraciflua) fruit, [2] which is abundant in North America, in yields of around 1.5%. For example, 4 kg (8.8 lb) of sweetgum seeds is needed for fourteen packages of Tamiflu. By comparison, star anise has been reported to yield 3% to 7% shikimic acid.
