Screening and identification of 3-aryl-quinolin-2-one derivatives as antiviral agents against influenza A

Quinolin-2-one represents an important and valuable chemical motif that possesses a wide variety of biological activities; however, the anti-influenza activities of quinolin-2-one-containing compounds were rarely reported. Herein, we describe the screening and identification of 3-aryl-quinolin-2-one derivatives as a novel class of antiviral agents. The 3-aryl-quinolinone derivatives were synthesized via an efficient copper-catalyzed reaction cascade that we previously developed. Using this synthetic method, preliminary structure–activity relationships of this scaffold against the influenza A virus infection were systematically explored. The most potent compound 34 displayed IC₅₀ values of 2.14 and 4.88 μM against the replication of H3N2 (A/HK/8/68) and H1N1 (A/WSN/33) strains, respectively, without apparent cytotoxicity on MDCK cells. We further demonstrated that 27 and 34 potently inhibited the plaque formation of the IAV, rendering this scaffold attractive for pursuing novel anti-influenza agents.     

Phase I-II study of gamma interferon and 5-fluorouracil for patients with metastatic renal cell carcinoma

We have completed a phase I/II trial to evaluate the toxicity and efficacy of the combination of gamma interferon and 5-fluorouracil in metastatic renal cell carcinoma. Gamma interferon was administered at a weekly dose of 100 micrograms. 5-fluorouracil was given as a 5 day continuous infusion days 1-5 of each 21 day cycle. In the phase I portion of the trial, the gamma interferon dose was held constant, while the 5-fluorouracil was escalated from 500 to 800 mg/m2/day. Serum neopterin and beta 2 microglobulin were measured prior to and 48 hours after each dose of gamma interferon for the first six weeks of treatment. Dose limiting toxicity was not encountered in the phase I part of the trial; therefore the phase II study was initiated at the 800 mg/m2/day dose of 5-fluorouracil. No responses were seen among 34 patients treated on the phase II trial. Forty-six percent of patients experienced disease stabilization and the remainder progressed through treatment. In the phase I trial, increments in neopterin and beta 2 microglobulin levels differed significantly between patients treated with lower and higher doses of 5-fluorouracil. We conclude that the addition of 5-fluorouracil to gamma interferon does not appear to enhance the cytokines clinical activity. Incremental increases in macrophage activation markers with escalating 5-fluorouracil doses suggests a role for 5-fluorouracil beyond its usual proposed cytotoxic activity and warrants further investigation into potential immunologic effects of this drug.     

Motility Disorders after Roux-en-Y Gastrojejunostomy

About 30% of patients who have a Roux-en-Y gastrojejunostomy after gastrectomy suffer from abdominal pain, nausea, vomiting of food and bloating made worse by eating. This syndrome, called the Roux stasis syndrome, is caused, in part, by a motility disorder of the Roux limb. Transection of the jejunum during the construction of the limb separates the limb from the natural small intestinal pacemaker located in the duodenum. Ectopic pacemakers then appear in the limb and trigger retrograde contractions in its proximal portion. These contractions slow transit through the limb and result in Roux stasis. Current nonsurgical treatment of the syndrome includes the use of prokinetic agents and intestinal pacing, neither of which has demonstrated long-term benefits. A near-total gastrectomy may speed upper gastrointestinal transit somewhat, but stasis in the Roux limb often persists. Our current approach aims at preventing the syndrome by the use of an ‘uncut’ Roux limb, an operation which preserves myoneural continuity between the duodenal pacemaker and the Roux limb and so prevents the appearance of ectopic pacemakers and stasis in the limb.

Knee dislocation: treatment of high-velocity knee dislocation

BACKGROUND: We report the outcomes of patients treated with a new arthroscopic treatment modality for knee dislocation after high-velocity trauma. METHODS: Twenty-three patients (12 men, 11 women; 25 knees) with traumatic knee dislocation were treated with this technique. Under arthroscopy with gravity inflow irrigation, the ruptured posterior cruciate ligament was reconstructed with a patellar bone-tendon-bone graft, and the anterior cruciate ligament was debrided subacutely. The collateral ligament, meniscus, and capsules were repaired through additional incisions. RESULTS: The average interval between injury and surgery was 11.1+/-5 days (range, 5 to 25 days). After a mean follow-up period of 27.2+/-7.86 months, the mean extension was 1+/-2 degrees and the average flexion was 129.6+/-4.91 degrees. The mean Lysholm score was 84. There were no major complications. CONCLUSION: Arthroscopic posterior cruciate ligament reconstruction seems to be an effective treatment for traumatic knee dislocation.
