Synthesis and Evaluation of Thiazoloquinolinones with Linkers To Enable Targeting of CD38.

Several monoclonal antibodies and inhibitors targeting CD38, an ectoenzyme overexpressed on malignant plasma cells, have previously been discovered. Herein, we expand structure-activity relationships of reported small-molecule thiazoloquinolinones and show that several 4-cyclohexylamino analogues have potent binding affinity for CD38 using surface plasmon resonance. Moreover, active amine analogues could be acylated and functionalized with alkyne and fluorescein groups.

Safety and efficacy of single-stage conversion of failed adjustable gastric band to laparoscopic Roux-en-Y gastric bypass: a case-control study.

Background: We conducted the following study to evaluate the safety and efficacy of single-stage conversion of failed laparoscopic adjustable gastric band (LAGB) to laparoscopic Roux-en-Y gastric bypass (LRYGB) as compared to a cohort of primary LRYGB patients.

Methods: A single-institution, prospectively maintained bariatric database was used to retrospectively identify consecutive patients who underwent single-stage removal of LAGB with concomitant conversion to LRYGB between the years of 2007 and 2013. The study cohort was matched 1:1 for age, gender, body mass index (BMI), and approximate date of operation to patients who underwent primary LRYGB.
