Spiro-[indene-1,1'-benzo[e]indolin]-2'-one.

ABSTRACT: In the title compound, C(20)H(13)NO, the indene ring is disordered over two sites with an occupancy ratio of 0.557?(2):0.443?(2). Both disordered components of indene are nearly perpendicular to the naphthalene ring system, making dihedral angles of 90.9?(2) and 85.0?(5)°. The five-membered ring of the 1H-pyrrol-2(3H)-one adopts an envelope conformation with the spiro C atom at the flap position. Inter-molecular classical N-H?O and weak C-H?O hydrogen bonding is present in the crystal structure.

5-Amino-5'-bromo-6-(4-methyl-benzo-yl)-8-nitro-2,3-di-hydro-1H-spiro-[imidazo[1,2-a]pyridine-7,3'-indolin]-2'-one including an unknown solvate.

Project description:In the title compound, C22H18BrN5O4, the central six-membered ring, derived from 1,4-di-hydro-pyridine, adopts a distorted boat conformation with a puckering amplitude of 0.197?(3)?Å, the imidazole ring adopts a twisted conformation with a puckering amplitude of 0.113?(3)?Å, and the oxindole moiety is planar with an r.m.s. deviation of 0.0125?Å. Two intra-molecular N-H?O hydrogen bonds are formed, each closing an S(6) loop. In the crystal, strong N-H?O hydrogen bonds lead to the formation of zigzag chains along the c axis. These are consolidated in the three-dimensional crystal packing by weak N-H?O hydrogen bonding, as well as by C-H?O, C-H?Br and C-H?? inter-actions. A small region of electron density well removed from the main mol-ecule was removed with the SQUEEZE procedure in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155] following unsuccessful attempts to model it as a plausible solvent mol-ecule. The unit-cell characteristics do not take into account this feature of the structure.

Development of spiro-3-indolin-2-one containing compounds of antiproliferative and anti-SARS-CoV-2 properties.

Project description:A series of 1″-(alkylsulfonyl)-dispiro[indoline-3,2'-pyrrolidine-3',3″-piperidine]-2,4″-diones 6a‒o has been synthesized through regioselective multi-component azomethine dipolar cycloaddition reaction of 1-(alkylsulfonyl)-3,5-bis(ylidene)-piperidin-4-ones 3a‒h. X-ray diffraction studies (6b‒d,h) confirmed the structures. The majority of the synthesized analogs reveal promising antiproliferation properties against a variety of human cancer cell lines (MCF7, HCT116, A431 and PaCa2) with good selectivity index towards normal cell (RPE1). Some of the synthesized agents exhibit potent inhibitory properties against the tested cell lines with higher efficacies than the standard references (sunitinib and 5-fluorouracil). Compound 6m is the most potent. Multi-targeted inhibitory properties against EGFR and VEGFR-2 have been observed for the synthesized agents. Flow cytometry supports the antiproliferation properties and shows the tested agents as apoptosis and necrosis forming. Vero cell viral infection model demonstrates the anti-SARS-CoV-2 properties of the synthesized agents. Compound 6f is the most promising (about 3.3 and 4.8 times the potency of the standard references, chloroquine and hydroxychloroquine). QSAR models explain and support the observed biological properties.

Crystal structure of 5-amino-5'-chloro-6-(4-chloro-benzo-yl)-8-nitro-2,3-di-hydro-1H-spiro-[imidazo[1,2-a]pyridine-7,3'-indolin]-2'-one including an unknown solvent mol-ecule.

Project description:The asymmetric unit of the title compound, C21H15Cl2N5O4, contains two independent mol-ecules (A and B) having similar conformations. The amine (NH2) group forms an intra-molecular hydrogen bond with the benzoyl group, giving an S(6) ring motif in both mol-ecules. The central six-membered rings adopt sofa conformations and the imidazole rings are planar (r.m.s deviations = 0.0150 and 0.0166 Å). The pyridine and imidazole rings are inclined to one another by 3.54 (1) and 3.03 (1)° in mol-ecules A and B, respectively. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, forming chains along the a axis which enclose R 2 (2)(16) ring motifs. The rings are linked by weak N-H⋯O and C-H⋯O hydrogen bonds and C-H⋯π inter-actions forming sheets lying parallel to (001). A region of disordered electron density, most probably disordered solvent mol-ecules, occupying voids of ca 753 Å(3) for an electron count of 260, was treated using the SQUEEZE routine in PLATON [Spek (2009 ▶). Acta Cryst. D65, 148-155]. Their formula mass and unit-cell characteristics were not taken into account during refinement.
