A series of novel asymmetrical mono-carbonyl analogs of curcumin (AMACs) were synthesized and evaluated for cytotoxic activity using BSLT and MTT assay against Vero, HeLa, and MCF7 cell lines. The structures of the synthesized compounds were confirmed by FTIR, 1H-NMR, 13C-NMR, and mass spectral data. The results of the cytotoxicity evaluation showed that the synthesized compounds exhibited moderate to very high toxic activity in BSLT (LC50 value 29.80–1704.23 µM); most of the compound exhibited cytotoxic activity against HeLa cell lines, which is comparable to the activity of cisplatin (IC50 value 40.65–95.55 µM), and most of the compound tested against MCF7 cell lines exhibited moderate to very high cytotoxic activity (IC50 value 7.86–35.88 µM). However, the selectivity index (SI) of the compounds was low (<1–1.96). Among the synthesized compounds, compound 1b was the most cytotoxic and selective against MCF7 cell lines. It could be considered for further development to obtain the more active and selective chemotherapeutic agents against breast cancer.
abstract:Objectives: This study aimed to evaluate the role of a clinical pharmacist intervention in decreasing subsequent clinical and drug-related problems (DRPs) among coronary heart disease (CHD) inpatients with at least one previous DRP. Methods: This pre-experimental study with a pre-post design was carried out from January to April 2017 among inpatients with at least one previous DRP at a general hospital in Tangerang District, Banten, Indonesia. Clinical and DRPs were documented prospectively by a clinical pharmacist, with DRPs classified using Version 6.2 of the DRP classification scheme of the Pharmaceutical Care Network Europe Foundation. The intervention consisted of a discussion of identified DRPs with physicians, patients, pharmaceutical logistics clerks, nurses and nutritionists. Following this, any subsequent clinical and DRPs were re-identified and further interventions were conducted as necessary. Results: A total of 75 inpatients were included in the study. Pre-intervention, there were 443 DRPs and 202 clinical problems. The most frequent DRPs were adverse drug reactions (52.6%), followed by drug effects (41.8%). Most DRPs were of moderate severity and would have resulted in moderate consequences had the pharmacist not intervened. The interventions resulted in a significant reduction in the number of DRPs, type of DRPs and number of clinical problems (P <0.05 each). Patients with complications were 26.047 times more likely to have no reduction or an increased number of clinical problems compared to patients without complications (P <0.05). Conclusion: Clinical pharmacist interventions were found to reduce subsequent DRPs and clinical problems among CHD patients with at least one previous DRP.

Objective: To analyze the effects of the topical gel that consists of quercetin nanoparticles on the mono iodoacetate-induced osteoarthritis.
Methods: Injection of lecithin-quercetin into chitosan-tocopheryl polyethylene glycol succinate (TPGS) was used to prepared quercetin nanoparticle. Evaluation parameter for the quercetin nanoparticle including polydispersity index, zeta potential, particle size using particle size analyzer and morphology were executed using a transmission electron microscope. The evaluation of quercetin nanoparticle gel includes organoleptic and also a homogeneity of quercetin nanoparticle gel includes pH and viscosity. Quercetin nanoparticle gel was given for osteoarthritis (OA) animal model. The amount dosage of quercetin nanoparticle used in this study was 0.84, 1.68, and 3.37 mg/g gel. Measurement of the edema volume was conducted on day 7, 14, 21, 28, 35, 42, 49, 56, 63, and 70.
Results: The quercetin nanoparticle gel dosage 1, 2, and 3 could reduce inflammation on two osteoarthritis animal models. On DMM group, 14 d after the treatment, there were significant differences between negative group and dosage 3 (P=0.028) and A. conyzoides extract gel (P=0.015). It has shown that injection of mono iodoacetate intraarticularly significantly increased the volume of edema in all groups that had been given by mono iodoacetate on day 7 to day 28. On the 42 d after administration of quercetin nanoparticle gel, there were significant differences between the normal and dosage 3 group (P= 0.000).
Conclusion: Quercetin nanoparticle gel could reduce inflammation and prevent cartilago damage on histological evaluation.
