koreanus in response xenobiotic-induced oxidative stress. The assembled B. koreanus genome will provide a better understanding on the molecular ecotoxicology in the view of molecular mechanisms underlying toxicological responses, particularly on xenobiotic detoxification processes in the rotifer B. koreanus. Herbicides are an integral part of global agricultural activity but can be advected into local drainages that can discharge to coastal marine systems. Herbicide runoff can impact coastal marine organisms, including those associated with coral reefs and coastal mangrove forests. In this study, the symbiotic sedentary jellyfish Cassiopea maremetens were exposed to analytical grade hexazinone to determine their sensitivity and potential for recovery after exposure to a press herbicide event of 14 days followed by a recovery period of matching duration. Bell surface area, photosynthetic yield (i.e. effective quantum yield, EQY), statolith count and zooxanthellae density were analyzed. Most metrics demonstrated significant decreases when exposed to higher concentrations of hexazinone, while EQY was significantly decreased at exposure concentrations from 31 μg/L hexazinone and above. In contrast, zooxanthellae density (cells/mm2) increased in the highest concentrations compared to control animals. At the end of the exposure period the EC50 for bell surface area, EQY, and statolith count were 176 μg/L, 81.96 μg/L, and 304.3 μg/L, respectively. Jellyfish were able to recover to similar start values for all measured metrics at the end of the 14-day recovery period, with EQY showing recovery by Day 7 of the recovery period. This study demonstrated that statolith counts as an estimate of age were not affected by herbicides. We conclude that the depressed metrics from herbicide related impacts of C. maremetens are effective indicators of a relatively recent herbicide perturbation in that the recovery timeframe for these jellyfish is relatively short. A new series of 2,4-dimethyl-1H-pyrrole-3-carboxamide derivatives bearing benzimidazole moiety was synthesized through a molecular hybridization approach and evaluated for in vitro anticancer activity by NCI-60 on leukemia, melanoma, lung, colon, CNS, ovarian, renal, prostate and breast cancer cell lines at a single dose (10 µM). Among all the synthesized conjugates, some derivatives showed more or less good activity even at such a small dose, while, compound 5-(1H-benzo[d]imidazol-2-yl)-N-(1-cyclohexylethyl)-2,4-dimethyl-1H-pyrrole-3-carboxamide (8f) displayed significant antiproliferative activity specifically against MDA-MB human cancer cell lines. Compound 8f showed promising activity against MDA-MB-435 cell line of melanoma (Growth inhibition 62.46%) and MDA-MB-468 cell line of breast (Growth inhibition 40.24%). Computational ADME study qualified its significant physicochemical, pharmacokinetic and drug-likeness properties with good predicted oral bioavailability. Exatecan purchase Thus this new hybrid molecules would be useful for further anticancer drug development. A series of novel 4-butyl-arylpiperazine-3-(1H-indol-3-yl)pyrrolidine-2,5-dione derivatives were synthesized and evaluated for their 5-HT1A/D2 receptor affinity and serotonin reuptake inhibition. The compounds exhibited high affinity for the 5-HT1A receptor, (especially 4dKi = 0.4 nM) which depended on the substitution pattern at the phenylpiperazine moiety. From this series screen, compound 4c emerged with promising mixed receptor profiles for the 5-HT1A/D2 receptors and the serotonin transporter (Ki = 1.3 nM, 182 nM and 64 nM, respectively). A novel photoantimicrobial agent, namely 2-aminothiazolo[4,5-c]-2,7,12,17-tetrakis(methoxyethyl)porphycene (ATAZTMPo-gentamicin) conjugate, has been prepared by a click reaction between the red-light absorbing 9-isothiocyanate-2,7,12,17-tetrakis(methoxyethyl)porphycene (9-ITMPo) and the antibiotic gentamicin. The conjugate exhibits
