Abstract
Receptors are proteinous macromolecules which remain in the apo form under normal/unliganded conditions. As the ligand approaches, there are specific stereo-chemical changes in the apo form of the receptor as per the stereochemistry of a ligand. Accordingly, a series of substituted dimethyl-chroman-based stereochemically flexible and constrained Tamoxifen analogs were synthesized as anti-breast cancer agents. The synthesized compounds 19a-e, 20a-e, 21, and 22a-e, showed significant antiproliferative activity against estrogen receptor-positive (ER+, MCF-7) and negative (ER-, MDA MB-231) cells within IC50 value 8.5-25.0 µM. Amongst all, four potential molecules viz 19b, 19e, 22a, and 22c, were evaluated for their effect on the cell division cycle and apoptosis of ER+ and ER- cancer cells (MCF-7 & MDA MB-231cells), which showed that these compounds possessed antiproliferative activity through triggering apoptosis. In-silico docking experiments elucidated the possible affinity of compounds with estrogen receptors-α and -β.

Synthesis and biological evaluation of substituted amide derivatives of C4-ageratochromene dimer analog. Bioorg Med Chem Lett 2021; 50:128340. [PMID: 34469711 DOI: 10.1016/j.bmcl.2021.128340] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2021] [Revised: 08/19/2021] [Accepted: 08/21/2021] [Indexed: 12/22/2022]
Abstract
Substituted amide derivatives of C4-ageratochromene dimer analog (19) were synthesized through structural modification of precocene-I (4a), isolated from the essential oil of Ageratum conyzoides L. The target compounds (18-20, 23I-VI, 24I-VI, and 25I-VI) were evaluated for their bone-forming effect using osteoblast differentiation assay. Seven compounds (23I, 23II, 23IV, 23VI, 24III, 24VI, and 25VI) presented good activity within 1 pM-1 nM concentration. At 1 pM concentration, the most active compound i.e. 23II showed effective mineralization of osteoblast cells along with expression of osteogenic marker genes viz RUNX 2, BMP-2, and type 1 collagen (Type-1 col) without any toxicity towards osteoblast cells. Single crystal X-ray analysis of 18 and 20 revealed that the core nucleus of these molecules bear phenyl rings in a Trans-stilbenoid system and had a good structural correlation with 17β-estradiol (1) and diethylstilbestrol (DES, 3). In-silico study about 23II showed its structural complementarities with the LBD of estrogen receptor (ER) which indicated possible ER-mediated activity of compounds.

Abstract
4-Methylenechromanes were prepared via a three-step process from 2-borylated α-methylstyrenes. This sequence is based on a key glyoxylate-ene reaction catalyzed by scandium(iii) triflate. The resulting γ-hydroxy boronates, which cyclise to seven-membered homologues of benzoxaborole on silica gel, were cleanly oxidized with sodium perborate, and then cyclised under Mitsunobu conditions. Additionally, several further functional transformations of 4-methylenechromanes or their precursors were carried out to illustrate the synthetic potential of these intermediates.
