A retrospective cohort study assessing acute kidney injury and renal recovery among septic patients empirically treated with vancomycin piperacillin-tazobactam versus vancomycin cefepime.

Vancomycin plus piperacillin-tazobactam (VPT) is a commonly used antimicrobial regimen for septic patients. VPT is more nephrotoxic than other regimens such as vancomycin plus cefepime (VC) when given over several days. This risk of nephrotoxicity is less clear when VPT is given for initial empiric therapy in sepsis and de-escalated quickly based on evolving clinical information.

Ceftaroline for meticillin-resistant Staphylococcus aureus bacteraemia: case series and review of the literature.

Data regarding ceftaroline use for meticillin-resistant Staphylococcus aureus bacteraemia (MRSAB) are lacking. Here we review the outcomes of 31 patients with MRSAB treated with ceftaroline, including 9 patients with endocarditis. Clinical success was observed in 23 patients (74.

Ceftaroline-induced eosinophilic pneumonia.

We present a case of eosinophilic pneumonia due to ceftaroline used for the treatment of methicillin-resistant Staphylococcus aureus bacteremia associated with a postoperative spinal infection. Our patient developed shortness of breath and hypoxemia on the fifth week of ceftaroline therapy. Chest imaging disclosed diffuse bilateral infiltrates.

Discovery of N-methyl-4-(4-methoxyanilino)quinazolines as potent apoptosis inducers. Structure-activity relationship of the quinazoline ring.

As a continuation of our efforts to discover and develop apoptosis inducing N-methyl-4-(4-methoxyanilino)quinazolines as novel anticancer agents, we explored substitution at the 5-, 6-, 7-positions of the quinazoline and replacement of the quinazoline by other nitrogen-containing heterocycles. A small group at the 5-position was found to be well tolerated. At the 6-position a small group like an amino was preferred.

Discovery of N-(4-methoxyphenyl)-N,2-dimethylquinazolin-4-amine, a potent apoptosis inducer and efficacious anticancer agent with high blood brain barrier penetration.

As a continuation of our structure-activity relationship (SAR) studies on 4-anilinoquinazolines as potent apoptosis inducers and to identify anticancer development candidates, we explored the replacement of the 2-Cl group in our lead compound 2-chloro-N-(4-methoxyphenyl)-N-methylquinazolin-4-amine (6b, EP128265, MPI-0441138) by other functional groups. This SAR study and lead optimization resulted in the identification of N-(4-methoxyphenyl)-N,2-dimethylquinazolin-4-amine (6h, EP128495, MPC-6827) as an anticancer clinical candidate. Compound 6h was found to be a potent apoptosis inducer with EC(50) of 2 nM in our cell-based apoptosis induction assay.
