JOURNAL OF HAZARDOUS MATERIALS 2020; 392:122291. [PMID: 32105953 DOI: 10.1016/j.jhazmat.2020.122291] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/22/2019] [Revised: 01/25/2020] [Accepted: 02/12/2020] [Indexed: 06/10/2023]
Abstract
In this paper, a simple chemical precipitation method was proposed to obtain zoledronate functionalized hydroxyapatite (zole-HAP) hybrid nano- biomaterials (zole-HAP-HNBM) which were firstly applied to adsorption. The characterizations of materials verified that the addition of zoledronate declined the crystallinity and transformed the morphology of HAP from short rod shape to microsphere, changed micro structure of the hybrid nanobiomaterial. Adsorption experiments carried out under different conditions showed that adsorption capacity of the nanobiomaterial, enhanced by the addition of zoledronate in preparation, which is equal to 1460.14 mg/g on Pb2+ and 226.33 mg/g on Cu2+ in optimum qualifications, was elevated more than the reported values in many literatures. At last, the sorption mechanisms of HAP and zole-HAP for Pb2+and Cu2+ were probed by experiments and Multifwn program calculation in details. It suggested that the dominant sorption mechanisms of HAP for Pb2+ were ion exchange and dissolution-precipitation rather than surface complexation, while besides the dissolution-precipitation mechanism, surface complexation may contribute more in the adsorption process of 10zole-HAP for Pb2+. Once considering HAP and 10zole-HAP, removal mechanisms of Cu2+ could involve surface complexation and ion exchange.

Abstract
A method to prepare four (3a–d) trialkyl alkylcarbonate esters of etidronate from P,P'-dimethyl etidronate and alkyl chloroformate was developed by utilizing unexpected demethylation and decarboxylation reactions. The reaction with the sterically more hindered isobutyl chloroformate at a lower temperature (90 °C) produced the P,P'-diester (2) as a stable intermediate product. A possible reaction mechanism is discussed to explain these methyl substitutions. These unusual reactions also clarify why it is difficult to prepare alkylcarbonate prodrugs from bisphosphonates. The compounds prepared were analysed by spectroscopic techniques.

Abstract
A general synthetic approach to two new series of methylenebisphosphonates: arylamino-2-ethane-1,1-diyl- and benzoxazole-2-methylenebisphosphonates is presented. Acid hydrolysis of selected BPs was undertaken to give the corresponding bisphosphonic acid (BP-acid). Next, the prediction of the permeability (hydrophobicity) of the target compounds was measured, by a combination of RP-HPLC and computational techniques, to study the capacity of transporting the molecule through cellular membranes. Cytotoxicity/growth inhibition of 50% (GI(50), mg/L) and antichronic inflammation properties of the products were evaluated. Later on, a comparison of the pharmacological results with water-octanol partition coefficients (log K(OW)) of the compounds was also reported.

Abstract
Aminobisphosphonates, e.g., alendronate and neridronate, are a well known class of molecules used as drugs for various bone diseases. Although these molecules have been available for decades, a detailed understanding of their most important physicochemical properties under comparable conditions is lacking. In this study, ten aminobisphosphonates, H2N(CH2)nC(OH)[P(O)(OH)2]2, in which n = 2–5, 7–11 and 15 have been synthesized. Their aqueous solubility as a function of temperature and pH, pKa-values, thermal stability, IR absorptions, and NMR spectral data for both liquid (1H, 13C, 31P-NMR) and solid state (13C, 15N and 31P-CPMAS NMR) were determined.

Abstract
A series of indole conjugated bisphosphonate derivatives have been synthesized and evaluated for their in vitro anti-bone resorptive activity using bone marrow osteoclast culture. Two bisphosphonates 23 and 24 significantly inhibited osteoclastogenesis, 23 showed inhibition at 10 and 100 pM which was lower than the concentration of standard drug alendronate, and 24 inhibited osteoclastogenesis at 100 nM which was comparable to alendronate. Two other compounds 13 and 14 also showed inhibition comparable to alendronate, but were cytotoxic in the osteoblast cells. The two active bisphosphonates 23 and 24 induced significant osteoclast apoptosis at concentrations 100 nM for compound 24 and at 10 pM for compound 23 compared to alendronate. In vivo effect of active bisphosphonates 23 and 24 resulted in osteoclastogenesis of bone marrow cells (BMCs) to almost 40-50% (23 showing 8.4% decrease and 24 showing 9.0%) compared to 16.5% of the ovariectomized group. Further, screening of anti-leishmanial activity, four compounds 24-25 and 27-28 showed more than 80% inhibition against both the promastigote and amastigote stages of the Leishmania parasite.

Abstract
An efficient general synthetic approach giving the possibility for facile, rapid and cheap access to a wide range of novel nitrogen-bisphosphonates (N-BPs) as potent drug candidates, based on the reaction of mono- and bis-propargyl-substituted bisphosphonates with a variety of azides under Cu(i) catalysis ("click" methodology), has been developed. The method allows the incorporation of two functionalities into the N-BP molecule simultaneously, as well as to ligate in situ two N-BPs to one another via the one-pot reaction of organic dibromides with propargyl-substituted bisphosphonates, generating both the diazide and Cu(I) moieties.

Abstract
The aim of the study was to compare the effects of once-weekly alendronate sodium and daily risedronate sodium treatment on bone mineral density (BMD) and bone turnover markers in postmenopausal osteoporotic subjects. For this purpose, 50 patients were included in this study and randomly classified into two groups. Group I (n=25) received risedronate (5 mg/day) and group II (n=25) received alendronate Na (70 mg/week). The study duration was limited to 12 months. The efficacy of the treatment was evaluated by BMD measurements at spine and hip at 6th and 12th months of the treatment, as well as by the measurement of bone turnover markers such as serum osteocalcin (OC), bone-specific alkaline phosphatase (BASP), urine deoxypyridinoline (DPD) and calcium/creatine ratio in 24-h urine at 1st, 3rd, 6th and 12th months. The evaluation of the changes in BMD in all regions revealed a significant increase in BMD in both groups compared to baseline values except for spine (L2-L4) in alendronate group at 6th and 12th month and femoral neck in risedronate group at 6th month. However, the difference in percentage increase in BMD measurements was not statistically significant between the two groups at 6th and 12th months. In both groups, serum OC, BSAP and urine DPD were found to be significantly attenuated at 1st month of the treatment period, and continued to be lowered throughout the 3rd, 6th and 12th months (P<0.05). However, there was no statistically-significant difference between both groups of patients (P>0.05). In conclusion, our results suggest that both treatment protocols provide treatment options of similar efficiency for postmenopausal osteoporosis, and have almost-similar effects in enhancing the BMD and in slowing the bone turnover. Risedronate seems to have a more potent effect in the spinal region than that of alendronate, although this potency was not statistically significant.

Abstract
Methods for the preparation of mixed tetra-amide esters 1 and 2, the partial amide ester 3, and tri- and P,P-diamides 4 and 5 from monophosphorus spieces 12, 8 and 9, respectively, were developed. Compounds 8 and 9 were obtained from phosphorus trichloride via MeOPCl2, which was treated with 2 eq. and 4 eq. of piperidine, followed by water or acetyl chloride, respectively. Tetrasubstituted amide bisphosphonates 1 and 2 were selectively dealkylated with lithium or silyl halide to achieve target compounds 3-5. Piperidine was found to be a good desilylation reagent. Quantum mechanical calculations illustrate why derivative 2 was produced in low yield. The usefulness of compounds 1, 3 and 4 as prodrugs of etidronate was determined in aqueous buffer and human serum.

Abstract
Cyclical etidronate has been shown to be effective in the treatment of established postmenopausal osteoporosis but less is known about its effects on early menopausal bone loss. The aim of the study was to establish the effects of cyclic etidronate therapy on spinal and proximal femoral bone mineral loss in early postmenopausal women. One hundred and seven women who were within 6 months to 3 years of the menopause were recruited into a 2-year, randomised, placebo-controlled, double-blind trial. Spinal bone mineral density was within 2 SD of the age-matched mean reference value at baseline. Bone mineral density in the lumbar spine and proximal femur was assessed by dual energy X-ray absorptiometry at baseline and thereafter at 6 monthly intervals for 2 years. Urinary collagen cross-links (deoxypyridinoline and pyridinoline) were measured at the same time points. Seventy-seven women completed the study. At the end of the treatment period, the mean bone mineral density change from baseline in the treated group was +0.14% and -0.06% in the lumbar spine and femoral neck, respectively, compared to -1.49 and -2.22 in the control group. Overall, there was a significant difference between the two groups at both these sites (p=0.01 and 0.001, respectively). No significant differences between the groups were demonstrated at the greater trochanter or Ward's triangle. The conclusion was that cyclical etidronate therapy prevents bone loss in the spine and femoral neck in early postmenopausal women. It provides a safe and effective therapeutic option for the prevention of postmenopausal osteoporosis in women who are unwilling or unable to tolerate hormone replacement therapy.

Abstract
Inorganic complexes have long been utilized for many therapeutic purposes. They were used or tried, perhaps because of the general notion that inorganic compounds (e.g., metal complexes) are toxic and a controlled use of such a compound may suppress some biological process. In this review, we briefly outline the properties of several selected groups of inorganic complexes and how they can affect biological systems and contribute to human pathologies.
