Novel lanthanide (Ln) compounds [Ln(L)2]Cl.xH2O (Ln = La3+, Ce3+, Sm3+) containing aromatic N,O-chelate ligands [HL1 = 4-amino-2-(1H-benzimidazol-2-yl)phenol; HL2 = 5-amino-2-(1H-benzimidazol-2-yl)phenol] have been synthesized and structurally characterized by elemental analysis, NMR and IR spectroscopy, molar conductance measurements, and mass spectrometry (MS). The spectroscopic data suggested that the benzimidazolyl-phenol ligands act as N,O-chelate ligands through the iminic nitrogen and phenolic oxygen atoms. Elemental analysis indicated that lanthanide compounds were formed in a 12 stoichiometry (metalligand). In vitro biological evaluation was carried out using these complexes, exhibiting moderate cytotoxicity against six different human tumor cell lines (U251, human glioblastoma; HCT-15, colorectal carcinoma; MCF-7, breast epithelial adenocarcinoma; PC-3, prostate cancer; K562, myelogenous leukemia; SKLU-1, lung carcinoma) and lower toxicity against a non-cancerous cell line (COS-7, primate kidney). Iration of the compounds increased. In addition, the main transition temperature was slightly reduced as a result of these interactions.In this study, the binding tendency of bisnitrophenoxy compounds (BN) having different methylene (-CH2-)n spacer groups (n = 8-11) with fish sperm double stranded deoxyribonucleic acid (dsDNA) was explored. Cyclic voltammetry (CV) was used to evaluate various kinetic and binding parameters (Ks,h, Do, K b and binding site sizes). Performed electrochemical studies designated strong contact of these symmetric molecules with dsDNA in threading intercalation mode of binding. The number (n) of methylene spacer group in the molecular structure of bisnitrophenoxy compounds, e.g., BN-8 (1-nitro-4-(8-(4-nitrophenoxy)octyloxy)benzene, was observed to have a strong influence on their binding affinity. Decreased peak current values and positively shifted peak potentials recorded via cyclic voltammetry clearly depicted that bisnitrophenoxy compounds can intercalate with dsDNA. Results demonstrated the following order of binding constants; K b (M-1) BN-8 (2.32 × 104) less then BN-9 (5.73 × 104) less then BN-10 (8.97 × 104) less then BN-11 (17.34 × 104). The order of increasing binding sites from BN-8 (0.13) to BN-11 (1.38), revealed the maximum threading intercalation strength by bisnitrophenoxy compound having the longest methylene spacer (n = 11). Thermodynamic studies augmented the strong binding of BN-11 with dsDNA as compared to BN-8 because of the long-chain, -CH2- spacer in its structure. The spontaneity of dsDNA-binding was revealed by the negative ΔG values for interaction of all the compounds. Moreover, binding parameters from thermodynamic and kinetic studies also corresponded to the threading intercalation mode of interaction, which itself points to the potency of the envisioned drug-like molecules.Development of efficient sequences for the synthesis of the title compound (2-(2,2-dimethoxyethyl)-1,2,3,4,5,6-hexahydro-1,5-methanoazocino[4,3-b]indole) (7) was described. The title compound was synthesized through several steps starting from phenylhydrazine hydrochloride and dimethyl (R)-2-(3-oxocyclohexyl)malonate. In this route, all synthesized compounds were observed by spectroscopic tools (FT-IR, NMR) Methyl-2-(2,3,4,9-1H-carbazol-2-yl)acetate (3), 2-(2,3,4,9-tetrahydro-1H-carbazol-2-yl)acetic acid (4), N-(2,2-dimethoxyethyl)-2-(2,3,4,9-tetrahydro-1H-carbazol-2-yl)acetamide (5), 2-(2,2-dimethoxyethyl)-1,2,4,5,6,7-hexahydro-3H-1,5-methanoazocino[4,3-b]indol-3-one (6), 2-(2,2-dimethoxyethyl)-2,3,4,5,6,7-hexahydro-1H-1,5-methanoazocino[4,3-b]indole (7). The central step in these syntheses is the dehydrogenative reaction, which constructs the tetracyclic ring system from a much simpler tetracyclic precursor. The six-stable conformers of the compound (7) were used for further calculations such as FT-IR, NMR, NLO, and FMO analyses, performed at the B3LYP/6-311++G(d,p) level. This work revealed that (7) can be a good material to use in the non-linear optical material because its β tensor is greater ten times than that of the urea.Purpose To compare the outcomes of patients with intermediate risk prostate cancer (IR-PCa) treated with low-dose rate I-125 seed brachytherapy (LDR-BT) and targeted dose painting of a histologic dominant intra-epithelial lesion (DIL) to those without a DIL. Methods 455 patients with IR-PCa were treated at a single center with intra-operatively planned LDR-BT, each following the same in-house dose constraints. Patients with a DIL on pathology had hot spots localized to that region but no specific contouring during the procedure.  https://www.selleckchem.com/Androgen-Receptor.html  Results 396 (87%) patients had a DIL. Baseline tumor characteristics and overall prostate dosimetry were similar between patients with and without DIL except the median number of biopsy cores taken 10 (10-12) vs 12 (10-12) (p = 0.002).19 (5%) and 18 (5%) of patients with and 1 (2%) and 0 (0%) of those without DIL experienced CTCAE grade 2 and 3 toxicity respectively. Overall, toxicity grade did not significantly correlate with presence of DIL (p = 0.10).Estimated 7-year freedom from biochemical failure (FFBF) was 84% (95% confidence interval 79-89) and 70% (54-89) in patients with and without a DIL (log-rank p = 0.315). In DIL patients, cox regression revealed location of DIL ("Base" vs "Apex" HR 1.03; 1.00-1.06; p = 0.03) and older age (70 vs 60 HR 1.62; 1.06-2.49; p = 0.03) was associated with poor FFBF. Conclusions Targeting DIL through dose painting during intraoperatively planned LDR-BT provided no statistically significant change in FFBF. Patients with DILs in the prostate base had slightly lower FFBF despite DIL boost.Osteoarthritis (OA) is a degenerative chronic disease that affects various tissues surrounding the joints, such as the subchondral bone and articular cartilage. The purpose of the study was to investigate the impact of collagen type III (CIII; 10 mg/kg; p.o.) on OA evidenced by restoration of articular cartilage structural changes as well as inflammatory responses using an established rat model of OA. OA was induced in rats by a single intra-articular injection of monosodium iodoacetate (MIA) through the right knee of the rats. Oral administration of CIII was undergone for 14 consecutive days. Changes in joint volume were measured throughout the experiment period with one-week intervals. At the end of the experiment, the rats were placed in the activity cage, and their activities were counted. Oxidative stress and nitrosative biomarkers were assessed by measuring the serum levels of malondialdehyde (MDA), reduced glutathione (GSH) and nitric oxide (NOx). Moreover, inflammatory markers viz. interleukin-6 (IL-6), interleukin-1β (IL-1β) and tumor necrosis nuclear factor-alpha (TNF-α) were measured.
