Heavy metal ions (HMIs) induce sever toxic and carcinogenic aspects through many mechanisms, which are not still understood. Therefore, the aim of this paper is to explorer new simple and efficient HMIs scavenger. In this endeavor, we have successfully fa

The main objective of this work to explore new safe antiviral agents against hepatitis A virus (HAV), norovirus (NoV) and Coxsackievirus B4 (CoxB4) infections. In this context, we have successfully prepared new polyquaternary phosphonium oligochitosans (P

Several series of 45 acetophenone derivatives bearing various alkyl or benzyl substituents were conveniently synthesized and their structures characterized by 1H and 13C NMR spectroscopy, HRMS and single-crystal X-ray analysis. Their in vitro antifungal activities against a panel of phytopathogenic fungi were evaluated by mycelial growth rate assay. Of them, 12 derivatives (e.g., 3a-c, 4c and 4e) exhibited more potent antifungal effects on some phytopathogens than a commercial fungicide hymexazol as positive control. In particular, compound 3b with IC50 values of 10-19μg/mL was found to be the most active in this series and might be a potential lead structure for further optimization. The preliminary structure-activity relationship (SAR) studies of a series of acetophenones are also discussed. A series of acetophenone derivatives have been synthesized and tested for their antifungal activities. Of them 12 derivatives exhibited more potent antifungal effects on some phytopathogens than a positive control hymexazol. Especially, compound 3b (IC50=10-19μg/mL) was found to be the most active and might be a potential lead structure. The SAR of these acetophenones is also discussed.

A series of new compounds structurally derived from 6a,12a-dihydro-6H,7H- [1]-benzopyran-[4,3-b]-benzopyran (homopterocarpane) was efficiently synthesized by reduction of the corresponding pyrilium salts obtained by treatment of selected flavanones and aldehydes with anhydrous HClO4. Cytotoxic effects on the human breast cancer cell line MCF-7 and antiestrogenic activity (only for compounds which resulted more active than tamoxifen (TAM)) on MCF-7 cells stimulated by 17β-estradiol were evaluated. In vivo antiestrogenic activity and the relative binding affinity were also assessed. Some of the new compounds (4c, 4h, 4i and 4l) showed a biological activity in the micromolar range, and were more potent than TAM taken as the reference.
7-[3-(1-piperidinyl)propoxy]chromenones as potential atypical antipsychotics. 2. Pharmacological profile of 7-[3-[4-(6-fluoro-1,2- benzisoxazol-3-yl)piperidin-1-yl] propoxy]-3-(hydroxymethyl)chromen-4-one (abaperidone, FI-8602)

A series of novel 7-[3-(1-piperidinyl)propoxy]chromenones was synthesized and tested as potential antipsychotics in several in vitro and in vive assays. The compounds possessed good affinity for D2 receptors, together with a greater affinity for 5-HT2 receptors, a profile which has been proposed as a model for atypical antipsychotics. Several agents also displayed a high potency in the climbing mice assay on oral administration, suggesting a potent antipsychotic effect as compared to reference standards. Compound 23 was selected for further pharmacological evaluation. Induction of catalepsy and inhibition of stereotypies weaker than standards, along with a lower increase in serum prolactin levels, were indicative of a potential atypical profile for this compound. From these results, 7-[3-[4-(6-fluoro- 1,2-benzisoxazol-3-yl)piperidin1-yl]propoxy]-3-(hydroxymethyl)chromen-4-one (23, abaperidone) has been proposed for clinical evaluation in humans as a potential atypical antipsychotic.

7-[3-(1-piperidinyl)propoxy]chromenones as potential atypical antipsychotics

Compound 1 (1-benzyl-3-methyl-4-[4-(4-fluorophenyl)-4- oxobutyl]piperazine), a synthetic intermediate identified as a potential atypical antipsychotic, was selected as the starting point for pharmacological improvement. From 1, sequential structural variations were conducted in order to improve its potency and oral bioavailability. These variations included a series of piperazine, ethanediamine, and piperidine derivatives. The piperidine series afforded some orally potent compounds in the inhibition of apomorphine-induced climbing and hyperactivity in mice, which are regarded as behavioral models predictive of antipsychotic efficacy. Further optimization of these structures led to the highly potent 7-[3-(1- piperidinyl)propoxy]chromenones. Inhibition of stereotypies and induction of catalepsy in rats at doses substantially higher than required for inhibition of climbing suggest an atypical antipsychotic profile, which is assumed to predict a reduced induction of extrapyramidal side effects in humans.
