In the present study, a novel series of 2-(2-(3-aryl-5-substituted-1,3,4-thiadiazol-2(3H)-ylidene)-hydrazinyl)-4,4-diphenyl-1H-imidazol-5(4H)-one derivatives were designed and prepared via the reaction of the most versatile, hitherto unreported 2-(5-oxo-4,4-diphenyl-4,5-dihydro-1H-imidazol-2-yl)-N-phenyl-hydrazinecarbothioamide with the appropriate hydrazonoyl halides. In addition, some thiazole derivatives were prepared. The structures of the newly synthesized compounds were established based on spectroscopic evidences and their alternative syntheses. Some of the newly synthesized compounds have been evaluated for their anticancer activity against a liver carcinoma cell line HEPG2-1. Moreover, their structure-activity relationship (SAR) was explored for further development in this area. The results indicated that many of the tested compounds showed moderate to high anticancer activity with respective to doxorubicin as a reference drug. Consequently, the new synthesized series of thiadiazole-imidazole derivatives are considered as powerful anticancer agents. © 2016 The Pharmaceutical Society of Japan.

Nebulising a bronchodilator during non-invasive ventilation (NIV) is effective but there is a lack of consensus on the system to use because comparator in vivo studies in these patients are difficult. Urinary pharmacokinetic methodology post inhalation could provide this information. Chronic obstructive pulmonary disease patients requiring NIV received randomised study doses of either 2mg terbutaline nebulised from an Aeroneb Pro (AERO) or 5mg from a Sidestream (SIDE) on days 1 and 3 of admission. Urine samples were provided at 30 min then pooled up to 24h post inhalation and amounts of urinary terbutaline (UTER0.5 and UTER24; indices of relative lung and systemic bioavailability, respectively) were determined. Twelve consenting patients receiving NIV mean (SD) age and weight of 74.8 (8.2) years and 61.0 (10.7)kg completed the study. The mean (SD) UTER0.5 following AERO and SIDE was 9.4 (3.7) and 10.4 (4.1) g with a mean ratio (90% confidence interval) of 89.7 (87.8, 92.3)%. UTER24 was 192.3 (52.4) and 205.3 (58.0)mcg with a mean ratio (90% CI) of 93.7 (113.5, 77.3)%. This urinary pharmacokinetic method to identity relative lung and systemic bioavailability between two nebuliser systems was easy to perform and is a useful and simple in vivo method to compare different nebulisers in patients receiving non-invasive ventilation.
