An innovative environmentally friendly deep eutectic solvent-based ligandless ultrasound-assisted liquid-phase microextraction was introduced for spectrophotometric determination of trace amount of cobalt. n-phenyliminodiacetic acid: choline chloride (2:1?mol ratio) as a novel DES was prepared for extraction of cobalt ions which is both as chelating agent and extraction solvent. The pivotal factors affecting the proposed method including pH, time, temperature, extraction solvent volume, ionic strength, and sample volume were investigated. At optimum conditions, limit of detection and limit of quantification of 5.23?μg?L?1 and 17.67?μg?L?1 were achieved respectively. The linear range of 20–200?μg?L?1 and precision (relative standard deviation %) of 3.4 for 100?μg?L?1 Co+2 solution were gained. The proposed method was successfully applied in water samples, tomato sauce, black and green tea, and dark chocolate with high recovery values (%) of 94–105.

About 30 analogues of BAPTA-AM, a potential antithrombotic agent, have been synthesized and tested for their effect on the production of prostacyclin.None of them was found to be a better enhancher of the production of prostacyclin by aortic endothelial cells than BAPTA-AM itself.The enhancing effect can be produced by compounds unable to chelate Ca2+, thus confirming that it is not related to their buffering capacity for free Ca2+.
