Abstract
This article describes our research work for the past decade, which involves the transition-metal-catalyzed cyclization reactions of the C-N multiple bonds containing species and their synthetic applications to access various heterocyclic compounds. The concepts of reactions including four types of coupling with a subsequent cyclization are (1) the transition-metal performs as a Lewis acid to activate a nitrile and accelerate the nucleophilic addition, (2) the transition-metal-catalyzed 1,2-insertion reaction of nitrile, (3) the Cu-catalyzed C-N coupling reaction of imine, and (4) the Co-catalyzed addition/cyclization reaction of imine. These methods can be used to synthesize various N-containing aromatic heterocycles with higher efficiency, and can be applied to the synthesis of relevent natural alkaloids, their derivatives as well as biologically active compounds.

A precisely substituted benzopyran targets androgen refractory prostate cancer cells through selective modulation of estrogen receptors. Toxicol Appl Pharmacol 2015; 283:187-97.

Abstract
Dietary consumption of phytoestrogens like genistein has been linked with lower incidence of prostate cancer. The estradiol-like benzopyran core of genistein confers estrogen receptor-β (ER-β) selectivity that imparts weak anti-proliferative activity against prostate cancer cells. DL-2-[4-(2-piperidinoethoxy)phenyl]-3-phenyl-2H-1-benzopyran (BP), a SERM designed with benzopyran core, targeted androgen independent prostate cancer (PC-3) cells 14-times more potently than genistein, ~25% more efficiently than tamoxifen and 6.5-times more actively than ICI-182780, without forfeiting significant specificity in comparison to genistein. BP increased apoptosis (annexin-V and TUNEL labeling), arrested cell cycle, and significantly increased caspase-3 activity along with mRNA expressions of estrogen receptor (ER)-β and FasL (qPCR) in PC-3 cells. In classical ERE-luc reporter assay BP behaved as a potent ER-α antagonist and ER-β agonist. Accordingly, it decreased expression of ER-α target PS2 (P<0.01) and increased expression of ER-β target TNF-α (P<0.05) genes in PC-3. ER-β deficient PC-3 (siRNA-transfected) was resistant to apoptotic and anti-proliferative actions of SERMs, including stimulation of FasL expression by BP. BP significantly inhibited phosphorylation of Akt and ERK-1/2, JNK and p38 in PC-3 (immunoblotting), and thus adopted a multi-pathway mechanism to exert a more potent anti-proliferative activity against prostate cancer cells than natural and synthetic SERMs. Its precise ER-subtype specific activity presents a unique lead structure for further optimization.

Abstract
Estrogen receptors alpha (ERα) and beta (ERβ) are nuclear transcription factors that are involved in the regulation of many complex physiological processes in humans. Modulation of these receptors by prospective therapeutic agents is currently being considered for prevention and treatment of a wide variety of pathological conditions, such as, cancer, metabolic and cardiovascular diseases, neurodegeneration, inflammation, and osteoporosis. This review provides an overview and update of compounds that have been recently reported as modulators of ERs, with a particular focus on their potential clinical applications.

Benzopyran derivative CDRI-85/287 induces G2-M arrest in estrogen receptor-positive breast cancer cells via modulation of estrogen receptors α- and β-mediated signaling, in parallel to EGFR signaling and suppresses the growth of tumor xenograft. Steroids 2013; 78:1071-86.

Abstract
In an endeavor to develop novel and improved selective estrogen receptor modulators as anti-breast cancer agents, the benzopyran compounds have been synthesized and identified which act as potent anti-estrogen at uterine level. The present study evaluates the anti-tumor activity of 2-[piperidinoethoxyphenyl]-3-phenyl-2H-benzo(b)pyran (CDRI-85/287) and explores the mechanism of action with a view to describe its potential to inhibit proliferation in ER-positive breast cancer cells MCF-7 and T47D. The compound decreased the expression of ERα while increased the expression of ERβ thereby altering ERα/ERβ ratio in both cell lines. Although the compound showed low binding affinity to ERs, it acted as ERα antagonist and ERβ agonist in decreasing ERE- or AP-1-mediated transcriptional activation in these cells. Transactivation studies in ERα/β-transfected MDA-MB231 cells suggested that at cyclin D1 promoter, compound antagonized the action of ERα-mediated E2 response while acted as estrogen agonist via ERβ. Further, the compound led to decreased expression of ERα-dependent proliferation markers and ERβ-dependent cell cycle progression markers. The expression of cell cycle inhibitory protein p21 was increased leading to G2/M phase arrest. In parallel, compound also interfered with EGFR activation, caused inhibition of PI-3-K/Akt pathway and subsequent induction of apoptosis via intrinsic pathway. A significant reduction in tumor mass and volume was observed in 85/287-treated mice bearing MCF-7 xenograft. We conclude that compound 85/287 exhibits significant anti-tumor activity via modulation of genomic as well as non-genomic mechanisms involved in cellular growth and arrested the cells in G2 phase in both MCF-7 and T47D breast cancer cells. Study suggests that CDRI-85/287 may have therapeutic potential in ER-positive breast cancer.

Abstract
Inhibition of epidermal growth factor receptor (EGFR) signaling is considered to be a promising treatment strategy for estrogen receptor (ER)-negative breast tumors. We have investigated here the anti-breast cancer properties of a novel anti-proliferative benzopyran compound namely, 2-[piperidinoethoxyphenyl]-3-phenyl-2H-benzo(b)pyran (CDRI-85/287) in ER- negative and EGFR- overexpressing breast cancer cells. The benzopyran compound selectively inhibited the EGF-induced growth of MDA-MB 231 cells and ER-negative primary breast cancer cell culture. The compound significantly reduced tumor growth in xenograft of MDA-MB 231 cells in nude mice. The compound displayed better binding affinity for EGFR than inhibitor AG1478 as demonstrated by molecular docking studies. CDRI-85/287 significantly inhibited the activation of EGFR and downstream effectors MEK/Erk and PI-3-K/Akt. Subsequent inhibition of AP-1 promoter activity resulted in decreased transcription activation and expression of c-fos and c-jun. Dephosphorylation of downstream effectors FOXO-3a and NF-κB led to increased expression of p27 and decreased expression of cyclin D1 which was responsible for decreased phosphorylation of Rb and prevented the transcription of E2F- dependent genes involved in cell cycle progression from G1/S phase. The compound induced apoptosis via mitochondrial pathway and it also inhibited EGF-induced invasion of MDA-MB 231 cells as evidenced by decreased activity of MMP-9 and expression of CTGF. These results indicate that benzopyran compound CDRI-85/287 could constitute a powerful new chemotherapeutic agent against ER-negative and EGFR over-expressing breast tumors.

Abstract
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 17beta-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.

Continuing our search for newer oestrogen agonists or antagonists and extending our work on the exploration of benzopyran related compounds, some new tricyclic molecules bridged between the active molecules of 3,4-diaryl chroman and 2,3-diaryl benzopyrans have been synthesised. Structural modifications at different positions with elements known to impart agonist or antagonist activities have been carried out to prepare the desired molecules. The target compounds were screened for their anti-osteoporotic (agonist) and anti-uterotrophic (antagonist) activities and were found to be moderately active.

Abstract
Antiosteoporotic activity of ormeloxifene, a multifunctional SERM, using inhibition in parathyroid hormone (PTH) induced resorption of 45Ca from prelabeled chick and rat fetal limb bones in chase cultures and modulation of certain biochemical markers of bone turnover and bone mineral density (BMD) in ovariectomized adult female rats, was investigated. Ormeloxifene concentration-dependently inhibited PTH-induced resorption of 45Ca from chick fetal femora with treated/control (T/C) ratio of 0.71, 0.32 and 0.20 at 50, 100 and 200 microM concentration, in comparison to 0.49, 0.53 and 0.95 in case of CDRI-85/287 (a pure antiestrogen), tamoxifen and ethynylestradiol (100 microM), respectively. Using rat fetal limb bones, ormeloxifene (100 microM) exhibited T/C ratio of 0.67, in comparison to 1.43 with PTH alone. Heat-killed bones exhibited negligible resorption (2.9%; T/C: 0.098) in response to PTH. In adult female rats, ormeloxifene (1.25 and 12.5 mg/kg per day) inhibited ovariectomy-induced increase in serum total and bone-specific alkaline phosphatase and osteocalcin and urine calcium/creatinine ratio to almost intact control level. Ovariectomy was accompanied by marked decrease in bone mineral density of isolated femur and tibia, being maximum in femur neck (28.3%; P < 0.01) and midshaft (23.7%; P < 0.01), but only marginal (6.7%; P > 0.05) in region proximal to tibio-fibular separation point. Decrease in BMD based on T-/Z-score, too, was >2.5 S.D. than mean value of normal young adult/age-matched females. This was prevented by ormeloxifene and the effect, though apparently more in females supplemented with higher dose of ormeloxifene, was not always significantly different and clear dose-response was not evident until BMD data was evaluated on T-/Z-score basis. The analysis also demonstrated much higher threshold level of tibia than femur and more so for their mid-shafts. Increase in BMD of isolated bones was also observed in ormeloxifene-treated intact females, without significantly altering biochemical markers of bone turnover or uterine weight. Findings suggest potential of ormeloxifene in management of post-menopausal osteoporosis and beneficial effect on BMD in women taking this SERM for contraception or any hormone-related clinical disorder.

Abstract
New compounds have been synthesized based on the structure of the anti-tumoral drug tamoxifen and its diphenylmethane derivative, N,N-diethyl-2-[(4-phenyl-methyl)-phenoxy]-ethanamine, HCl (DPPE). These new compounds have no affinity for the estrogen receptor (ER) and bind with various affinity to the anti-estrogen binding site (AEBS). Compounds 2, 10, 12, 13, 20a, 20b, 23a, 23b, 29 exhibited 1.1-69.5 higher affinity than DPPE, and compounds 23a and 23b have 1.2 and 3.5 higher affinity than tamoxifen. Three-dimensional structure analysis, performed using the intersection of the van der Waals volume occupied by tamoxifen in its crystallographic state and the van der Waals volume of these new compounds in their calculated minimal energy conformation, correlated well with their pKi for AEBS (r = 0.84, P<0.0001, n = 18). This is the first structure-affinity relationship (SAR) ever reported for AEBS ligands. Moreover in this study we have reported the synthesis of new compounds of higher affinity than the lead compounds and that are highly specific for AEBS. Since these compounds do not bind ER they will be helpful to study AEBS mediated cytotoxicity. Moreover our study shows that our strategy is a new useful guide to design high affinity and selective ligands for AEBS.

Abstract
Compound 1 (DL-2-[4-(2-piperidinoethoxy)phenyl]-3-phenyl-2H-1-benzopyran, CDRI 85/287) a potent anti-estrogen and anti-implantation agent has been successfully resolved into its pure D- and L-enantiomers. Biological studies showed L-enantiomer to be the active form, exhibiting a fivefold higher receptor affinity for the rat uterine cytosolic estrogen receptor, 100% contraceptive efficacy at 1.3 mg/kg dose in single day schedule and 89% inhibition of estradiol induced increase of uterine weight at its contraceptive dose. The absolute stereochemistry determined by X-ray crystallographic analysis showed that the L-enantiomer has 2R configuration at its asymmetric centre.

Abstract
In an endeavour to develop potent anti-implantation agents, a new antiestrogen, CDRI 85/287 (2-(4-2-piperidinoethoxy)phenyl-3-phenyl(2H)benzo(b)pyran), virtually devoid of agonistic activity, was identified. The present study deals with anti-implantation and estrogen agonistic-antagonistic activities of four structural analogues of 85/287. Results show that none of the compounds induced vaginal cornification, even at doses as high as 2.5 mg/kg. Compounds having p-hydroxyphenyl group at position-3 or hydroxy group at position-7 showed better estrogen receptor affinity (6.6 and 25.3% E2) as well as antiestogenic activity. When 3-p-hydroxyphenyl was replaced by 3-p-methoxyphenyl, a marked reduction in the receptor affinity was observed. However, this compound was relatively more potent as an anti-implantation agent, possibly due to its conversion to hydroxylated metabolite in vivo. The provision of aminoethoxy side chain at para-position and a shift in the piperidinoethoxy side chain from position-4 to position-2 in these molecules resulted in a decrease in estrogenicity and increase in antagonistic property. Results are discussed with regard to molecular configuration, relative binding affinity of these compounds to their biological profile.
