Abstract
A refined strategy has been developed to control the regioselective asymmetric (4+3) cyclization of α-(3-isoindolinonyl) propargylic alcohols with 2-indolylmethanols, utilizing chiral phosphoric acid catalysis. This innovative organocatalytic cyclization yields spiro isoindolinone-oxepine-fused indoles featuring a spiro-quaternary stereocenter in high yields and enantioselectivities, facilitated by the solvent of 1,1-dichloro-1-fluoroethane and the additive of hexafluoroisopropanol. Additionally, the photophysical properties of product 3k are examined, revealing bright fluorescence both in the solution and the solid state.

Abstract
We have developed a straightforward and efficient synthetic protocol to produce 5,6,7,12-tetrahydrobenzo[2,3]azepino[4,5-b]indole and 7,12-dihydro-6H-benzo[2,3]oxepino[4,5-b]indole derivatives under mild conditions. This annulation process involves the intramolecular cyclization of the in situ generated ketimine moiety via the formation of dihydrospiroindolequinoline, which serves as a key intermediate in the reaction pathway. Several control experiments and spectroscopic studies were performed to elucidate the underlying reaction mechanism.

Abstract
In the rapidly growing COVID-19 pandemic, designing of new drugs and evaluating their inhibitory action against main targets of corona virus could be an effective strategy to accelerate the drug discovery process and their efficacy towards corona virus disease. Herein, we design new bis-triazolyl probe for an investigation of inhibitory activity towards COVID-19 main protease by Molecular docking approach. The formulated compound has been thoroughly characterized by elemental analysis, NMR (1H and 13C) and complete structure elucidation was achieved via X-ray crystallography. Docking study reveals that newly synthesized compound confers good inhibitory response to COVID-19 main protease as supported by calculated docking score and binding energy. Strong hydrogen bonding and hydrophobic interactions of the newly synthesized compound with several important amino acids of the main protease also helps to explain the potency of the compound to inhibit the main protease. We hope that the present study would help the researcher in the field of Medicinal chemistry and to develop potential drug against the novel corona virus.

Abstract
Indibulin (D-24851) derivatives with bisphosphonate fragment connected to the N1 atom of imidazole ring were synthesized by alkylation of (indolyl-3)methylglyoxylates with ethylenebisphosphonate. Biological evaluation of targeted compounds 4a-d using the phenotypic sea urchin embryo assay provided evidence that replacing of p-chlorobenzene ring in indibulin by bisphosphonate group did not eliminate antimitotic microtubule destabilizing activity. The most active molecule, tetraacid 5a, at physiological pH formed tetrasodium salt 6a with aqueous solubility value of at least 10 mg/mL. Molecule 5a was more potent in the sea urchin embryo assay than the parent indibulin. This compound also exhibited pronounced cytotoxicity against A549 lung carcinoma and A375 melanoma cell lines.

Abstract
Irisin is a product of fibronectin type III domain-containing protein (Fndc5) and is involved in the regulation of adipokine secretion and the differentiation of osteoblasts and osteoclasts. In this study, we aimed to determine whether irisin lacking affects glucose/lipid and bone metabolism. We knocked out the Fndc5 gene to generate irisin-lacking mice. Remarkable, irisin lacking was related to poor 'browning response', with a bigger size of the intraperitoneal white adipose cell and decreased a number of brown adipose cells in brown adipose of interscapular tissue. The irisin lacking mice had hyperlipidemia and insulin resistance, reduced HDL-cholesterol level, increased LDL-cholesterol level, and decreased insulin sensitivity. The lacking of irisin was associated with reduced bone strength and bone mass in mice. The increased number of osteoclasts and higher expression of RANKL indicated increased bone resorption in irisin lacking mice. The level of IL-6 and TNF-α also increased in irisin lacking mice. The results showed that irisin lacking was related to decreased 'browning response', glucose/lipid metabolic derangement, and reduced bone mass with increased bone resorption. Further studies are needed to confirm these initial observations and explore the mechanisms underlying the effects of irisin on glucose/lipid and bone metabolism.

Abstract
BACKGROUND 1,2,3-triazoles are five-membered heterocyclic scaffold; their broad-spectrum biological activities are known. Researchers around the world are increasingly being interested in this emerging area, owing to its immense pharmacological scope. OBJECTIVE This work summarizes the synthesis of 1,2,3-triazoles and the significance of this pattern as a lead structure for new drug molecules discovery. METHODS 1,2,3-triazoles can be obtained on a multigram scale through "click chemistry" under ambient conditions. RESULTS Sixteen compounds were synthesized and evaluated on five microbial strains E. coli, E. faecalis, P. aeruginosa, S. aureus and C. albicans. NMR, MS and IR were used to characterize all compounds. They were evaluated with their Minimum Inhibitory Concentrations (MICs) and interesting results were obtained with compounds 12a, 12b, 3, 2a and 2c, with MIC 0.14 μM (P. aeruginosa), 1.08 μM (E. coli), 1.20 μM (E. faecalis and C. albicans), 3.5 μM (E. faecalis) and 4.24 μM (C. albicans), respectively. P. aeruginosa and C. albicans were the most sensitive among all the strains. CONCLUSION The synthesized compounds were found as potential antimicrobial agents against Gram (+), Gram (-) strains and fungi.

Abstract
Osteoporosis is an asymptomatic progressive disease. With the improvement of people's living standard and the aging of population, osteoporosis and its fracture have become one of the main diseases threatening the aging society. The serious medical and social burden caused by this has aroused wide public concern. Osteoporosis is listed as one of the three major diseases of the elderly. At present, the drugs for osteoporosis include bone resorption inhibitors and bone formation promoters. The purpose of these anti-osteoporosis drugs is to balance osteoblast bone formation and osteoclast bone resorption. With the development of anti-osteoporosis drugs, new anti osteoporosis drugs have been designed and synthesized. There are many kinds of new compounds with anti osteoporosis activity, but most of them are concentrated on the original drugs with anti osteoporosis activity, or the natural products with anti-osteoporosis activity are extracted from the natural products for structural modification to obtain the corresponding derivatives or analogues. These target compounds showed good ALP activity in vitro and in vivo, promoted osteoblast differentiation and mineralization, or had anti TRAP activity, inhibited osteoclast absorption. This work attempts to systematically review the studies on the synthesis and bioactivity of anti-osteoporosis drugs in the past 10 years. The structure-activity relationship was discussed, which provided a reasonable idea for the design and development of new anti-osteoporosis drugs.

Abstract
:
Due to their versatile biological activity, Azoles are widely studied in pharmacochemistry. It is possible
to use them in many applications and in studies aimed at discovering antiparasitic, antineoplastic, antiviral,
antimicrobial compounds; and in the production of materials for treatment of varied pathologies. Based on their
biological activity, our review presents several studies that involve this class of organic compounds. A bibliographic
survey of this type can effectively contribute to pharmaceutical sciences, stimulating the discovery of new
compounds, and structural improvements to biological profiles of interest. In this review, articles are discussed
involving the synthesis of new compounds and chemoinformatic contributions. Current applications of azoles in
both the pharmaceutical and agri-business sectors are well known, yet as this research highlights, azole compounds
can also bring important contributions to the fight against many diseases. Among the heterocyclics, azoles
are increasingly studied by research groups around the world for application against tuberculosis, HIV, fungal and
bacterial infections; and against parasites such as leishmaniasis and trypanosomiasis. Our hope is that this work
will help arouse the interest of research groups planning to develop new bioactives to fight against these and
other diseases.

Abstract
1,2,3-Triazoles are important five-membered heterocyclic scaffold due to their extensive biological activities. This framework can be readily obtained in good to excellent yields on the multigram scale through click chemistry via reaction of aryl/alkyl halides, alkynes and NaN3 under ambient conditions. It has been an emerging area of interest for many researchers throughout the globe owing to its immense pharmacological scope. The present work aims to summarize the current approaches adopted for the synthesis of the 1,2,3-triazole and medicinal significance of these architectures as a lead structure for the discovery of drug molecules such as COX-1/COX-2 inhibitors (celecoxib, pyrazofurin), HIV protease inhibitors, CB1 cannabinoid receptor antagonist and much more which are in the pipeline of clinical trials. The emphasis has been given on the major advancements in the medicinal prospectus of this pharmacophore for the period during 2008-2016.

Synthesis of new indole-based bisphosphonates and evaluation of their chelating ability in PE/CA-PJ15 cells. Eur J Med Chem 2015; 102:403-12.

Abstract
Bisphosphonates are the most important class of antiresorptive agents used against osteoclast-mediated bone loss, and, more recently, in oncology. These compounds have high affinity for calcium ions (Ca(2+)) and therefore target bone mineral, where they appear to be internalized selectively by bone-resorbing osteoclasts and inhibit osteoclast function. They are extensively used in healthcare, however they are affected by severe side effects; pharmacological properties of bisphosphonates depend on their molecular structure, which is frequently the cause of poor intestinal adsorption and low distribution. In this work we synthesized six novel bisphosphonate compounds having a variably substituted indole moiety to evaluate their extra- and intracellular calcium chelating ability in PE/CA-PJ15 cells. Preliminary in silico and in vitro ADME studies were also performed and the results suggested that the indole moiety plays an important role in cell permeability and metabolism properties.

A novel therapeutic approach with Caviunin-based isoflavonoid that en routes bone marrow cells to bone formation via BMP2/Wnt-β-catenin signaling. Cell Death Dis 2014; 5:e1422.

Abstract
Recently, we reported that extract of Dalbergia sissoo made from leaves and pods have antiresorptive and bone-forming effects. The positive skeletal effect attributed because of active molecules present in the extract of Dalbergia sissoo. Caviunin 7-O-[β-D-apiofuranosyl-(1-6)-β-D-glucopyranoside] (CAFG), a novel isoflavonoid show higher percentage present in the extract. Here, we show the osteogenic potential of CAFG as an alternative for anabolic therapy for the treatment of osteoporosis by stimulating bone morphogenetic protein 2 (BMP2) and Wnt/β-catenin mechanism. CAFG supplementation improved trabecular micro-architecture of the long bones, increased biomechanical strength parameters of the vertebra and femur and decreased bone turnover markers better than genistein. Oral administration of CAFG to osteopenic ovariectomized mice increased osteoprogenitor cells in the bone marrow and increased the expression of osteogenic genes in femur and show new bone formation without uterine hyperplasia. CAFG increased mRNA expression of osteoprotegerin in bone and inhibited osteoclast activation by inhibiting the expression of skeletal osteoclastogenic genes. CAFG is also an effective accelerant for chondrogenesis and has stimulatory effect on the repair of cortical bone after drill-hole injury at the tissue, cell and gene level in mouse femur. At cellular levels, CAFG stimulated osteoblast proliferation, survival and differentiation. Signal transduction inhibitors in osteoblast demonstrated involvement of p-38 mitogen-activated protein kinase pathway stimulated by BMP2 to initiate Wnt/β-catenin signaling to reduce phosphorylation of GSK3-β and subsequent nuclear accumulation of β-catenin. Osteogenic effects were abrogated by Dkk1, Wnt-receptor blocker and FH535, inhibitor of TCF-complex by reduction in β-catenin levels. CAFG modulated MSC responsiveness to BMP2, which promoted osteoblast differentiation via Wnt/β-catenin mechanism. CAFG at 1 mg/kg/day dose in ovariectomy mice (human dose ∼0.081 mg/kg) led to enhanced bone formation, reduced bone resorption and bone turnover better than well-known phytoestrogen genistein. Owing to CAFG's inherent properties for bone, it could be positioned as a potential drug, food supplement, for postmenopausal osteoporosis and fracture repair.

Abstract
IMPORTANCE OF THE FIELD Bones play many roles in the body, providing structure, protecting organs, anchoring muscles and storing calcium. Over 100 million people worldwide suffer from bone diseases, mainly osteoporosis, cancer-related bone loss, osteoarthritis and inflammatory arthritis. Osteoporosis itself has no specific symptoms, and the main consequence is the increased risk of bone fractures. Therefore, the prevention of bone diseases is important to maintain the quality of life in the human society. However, treatment options are still insufficient. AREAS COVERED IN THIS REVIEW This review article gives a summary of the low molecular mass modulators of bone diseases targets disclosed in patent applications and articles, mainly during the last 5 years. WHAT THE READER WILL GAIN Readers will rapidly gain an overview of these modulators not only for historical targets, but also of emerging and re-visited targets. Readers will also be able to see the current research trend and the main players in this field. TAKE HOME MESSAGE Drug discovery for bone diseases has made progress in the last years. The research area has dynamically shifted from historical targets (bisphosphonate, parathyroid hormone and calcitonin) to newly confirmed targets or targets re-visited which were biologically validated in the past. Cathepsin K inhibitors should be very close to launching in the market.

Abstract
The one pot reaction of amino acids with diethylphosphite and formaldehyde yielded N,N-bis(phosphonomethyl)amino acids. This synthetic route does not require harsh reagents to cleave the ester group. The molecular structures of the new compounds were determined by X-ray diffraction methods. By employing DFT calculations the hydrolysis of the intermediate phosphonic esters to the respective acids could be explained by the decreasing P-OEt bond strength for C(alpha)-bisalkylated amino acids. Biological evaluation on the adipogenic and osteogenic differentiation of mesenchymal stem cells revealed no modification of the adipocyte differentiation, but inhibition of osteoblast formation at concentrations without detectable cytotoxicity.
