http://clinicaltrials.gov/ct2/show/NCT01689142 reports clinical trials
To compare the efficacy of a new formulation of insulin glargine and Lantus in terms of change of HbA1c from baseline to endpoint (scheduled at month 6 [week 26]) in patients with type 2 diabetes mellitus.
Secondary Objectives:
- To compare a new formulation of insulin glargine and Lantus in terms of change in fasting plasma glucose, pre-injection plasma glucose, 8-point self-measured plasma glucose profile.
- To compare a new formulation of insulin glargine and Lantus in terms of occurrence of hypoglycemia
Insulin glargine is produced by recombinant DNA technology using a non-pathogenic laboratory strain of Escherichia coli (K12) as the production organism. It is an analogue of human insulin made by replacing the asparagine residue at position A21 of the A-chain with glycine and adding two arginines to the C-terminus (positions B31 and 32) of the B-chain. The resulting protein is soluble at pH 4 and forms microprecipitates at physiological pH 7.4. Small amounts of insulin glargine are slowly released from microprecipitates giving the drug a long duration of action (up to 24 hours) and no pronounced peak concentration.

Astellas’ Xtandi approved in EU for prostate cancer
enzalutamide
XTANDI
Regulators in European have given the green light to Astellas Pharma and Medivation’s oral prostate cancer drug Xtandi.
Specifically, the European Commission has approved Xtandi (enzalutamide) capsules for the treatment of men with metastatic castration-resistant prostate cancer whose disease has progressed on or after docetaxel therapy. The thumbs-up comes a couple of months after the European Medicines Agency’s Committee for Human Medicinal Productsissued a positive recommendation on the treatment….. READ ALL AT

Enzalutamide (marketed as Xtandi and formerly known as MDV3100) is an androgen receptor antagonist drug developed by the pharmaceutical company Medivation for the treatment of metastatic castration-resistant prostate cancer. Medivation has reported up to an 89% decrease in prostate specific antigen serum levels after a month of taking the medicine. Early preclinical studies also suggest that enzalutamide inhibits breast cancer cell growth. In August of 2012, the U.S. Food and Drug Administrationapproved enzalutamide for the treatment of castration-resistant prostate cancer.
Enzalutamide was discovered by Charles Sawyers who is now at Memorial Sloan–Kettering Cancer Center and Michael Jung at UCLA.

The antibiotic Vibativ (telavancin) has been approved by the U.S. Food and Drug Administration to treat pneumonia caused by Staphylococcus aureus bacteria
telavancin
The antibiotic Vibativ (telavancin) has been approved by the U.S. Food and Drug Administration to treat pneumonia caused by Staphylococcus aureus bacteria when other treatments aren’t suitable.
Pneumonia, a lung infection, can be caused by different bacteria and viruses. S. aureus infection often affects people in hospitals, notably those on ventilators. Such infections can be serious, since people on a ventilator often have a weakened immune system and are unable to fight an infection, the FDA said in a news release.http://www.drugs.com/news/vibativ-approved-certain-bacterial-pneumonia-45418.html
Telavancin (trade name Vibativ) is a bactericidal lipoglycopeptide for use in MRSA or other Gram-positive infections. Telavancin is a semi-synthetic derivative of vancomycin.
The FDA approved the drug in September 2009 for complicated skin and skin structure infections (cSSSI)
On 19 October 2007, the US Food and Drug Administration (FDA) issued an approvable letter for telavancin. Its developer, Theravance, submitted a complete response to the letter, and the FDA has assigned a Prescription Drug User Fee Act (PDUFA) target date of 21 July 2008.
On 19 November 2008, an FDA antiinfective drug advisory committee concluded that they would recommend telavancin be approved by the FDA.
The FDA approved the drug on 11 September 2009 for complicated skin and skin structure infections (cSSSI).
Theravance has also submitted telavancin to the FDA in a second indication, nosocomial pneumonia, sometimes referred to as hospital-acquired pneumonia, or HAP. On 30 November 2012, an FDA advisory panel endorsed approval of a once-daily formulation of telavancin for nosocomial pneumonia when other alternatives are not suitable. However, telavancin did not win the advisory committee’s recommendation as first-line therapy for this indication. The committe indicated that the trial data did not prove “substantial evidence” of telavancin’s safety and efficacy in hospital-acquired pneumonia, including ventilator-associated pneumonia caused by Gram-positive organisms Staphylococcus aureus and Streptococcus pneumoniae. On 21 June 2013 FDA gave approval for telavancin to treat patients with hospital-acquired pneumonia, but indicated it should be used only when alternative treatments are not suitable. FDA staff had indicated telavancin has a “substantially higher risk for death” for patients with kidney problems or diabetes compared to vancomycin.

June 24, 2013 , Astellas Pharma US, Inc. (“Astellas”), a U.S. subsidiary of Tokyo-based Astellas Pharma Inc. (Tokyo: 4503), announced that the U.S. Food and Drug Administration (FDA) has approved its Supplemental New Drug Application (sNDA) for the use of MYCAMINE® (micafungin sodium) for injection by intravenous infusion for the treatment of pediatric patients four months and older with candidemia, acute disseminated candidiasis, Candida peritonitis and abscesses, esophageal candidiasis, and prophylaxis of Candida infections in patients undergoing hematopoietic stem cell transplants (HSCT).
Micafungin (trade name Mycamine) is an echinocandin antifungal drug developed by Astellas Pharma. It inhibits the production of beta-1,3-glucan, an essential component of fungal cell walls. Micafungin is administered intravenously. It received final approval from the U.S. Food and Drug Administration on March 16, 2005, and gained approval in the European Union on April 25, 2008.
Micafungin is indicated for the treatment of candidemia, acute disseminated candidiasis, Candida peritonitis, abscesses and esophageal candidiasis. Since January 23, 2008, micafungin has been approved for the prophylaxis of Candida infections in patients undergoing hematopoietic stem cell transplantation (HSCT).
Micafungin works by way of concentration-dependent inhibition of 1,3-beta-D-glucan synthase resulting in reduced formation of 1,3-beta-D-glucan, which is an essential polysaccharide comprising one-third of the majority of Candida spp. cell walls. This decreased glucan production leads to osmotic instability and thus cellular lysis

QUINAPRIL
QUINAPRIL HYDROCHLORIDE
Quinapril (marketed under the brand name Accupril by Pfizer) is an angiotensin-converting enzyme inhibitor (ACE inhibitor) used in the treatment of hypertension andcongestive heart failure.
Quinapril inhibits angiotensin converting enzyme, an enzyme which catalyses the formation of angiotensin II from its precursor, angiotensin I. Angiotensin II is a powerfulvasoconstrictor and increases blood pressure through a variety of mechanisms. Due to reduced angiotensin production, plasma concentrations of aldosterone are also reduced, resulting in increased excretion of sodium in the urine and increased concentrations ofpotassium in the blood.

The condensation of alanine tert-butyl ester (I) with ethyl 2-bromo-4-phenylbutanoate (II) by means of triethylamine in hot DMF gives ethyl 2-[[1-(tert-butoxycarbonyl)ethyl]amino]-4-phenylbutanoate (III), which is partially hydrolyzed with trifluoroacetic acid yielding ethyl 2-[[1-carboxyethyl]amino]-4-phenylbutanoate (IV). The condensation of (IV) with tert-butyl-1,2,3,4-tetrahydroisoquinoline-3-carboxylate (VIII) [prepared from the corresponding acid (VI) and isobutylene (B) by means of H2SO4] as before gives tert-butyl-2-[2-[[1-(ethoxycarbonyl)-3-phenylpropyl]amino]-1-oxopropyl]-1,2,3,4-tetrahydroisoquinoline-3-carboxylate (IX), which is finally hydrolyzed partially by treatment with trifluoroacetic acid.Hoefle, M.L.; Klutchko, S.
