The design and synthesis of a phenoxazine-based metal-organic tetrahedron (Zn4L4) as biomimetic lectin for selectively recognition of glucosamine (GlcN) was reported. Different from the free phenoxazine-based ligand (L), Zn4L4 displayed the highest fluorescent intensity enhancement efficiency toward GlcN over other related natural mono- and disaccharides. Fluorescence titration demonstrated a 1:1 stoichiometric host-guest complex was formed with an association constant about 4.03 × 104 L/mol. 1H NMR spectroscopic studies confirmed this selectivity resulted from the multiple hydrogen bonding interactions formed between GlcN and Zn4L4. The present results suggested that rational arrangement of recognition sites in the confined space of metal-organic cage is crucial for the selectivity toward target guests.

The combination of commonly used FeCl3/SIPr with Ti(OEt)4/PhOM enabled a highly general iron-based catalyst system, which could efficiently catalyze the biaryl coupling reaction between various electrophiles (I, Br, Cl, OTs, OCONMe2, OSO2NMe2) and common or functionalized aryl Grignard reagents with high functional group tolerance. Selective couplings of aryl iodides and bromides over the corresponding oxygen-based electrophiles have been achieved, and thus a terphenyl acid intermediate for anidulafungin was conveniently synthesized via an orthogonal coupling strategy.

A new series of theophylline analogues containing 1,2,3-triazoles with different amide groups (22-41) has been designed and synthesized, and their biological activities have been evaluated as potential anticancer agents. The anticancer activities of the synthesized compounds were studied in four cancer cell lines viz. lung (A549), colon (HT-29), breast (MCF-7) and melanoma (A375). Furthermore, these compounds were screened for computational ADME and Lipinski's analysis followed by molecular docking and binding energy calculations against the various therapeutic targets involved in cell proliferation. The in vitro results demonstrate that compounds 22, 27, 36 and 40 have pivotal anticancer activity. Among these, compounds 22 and 27 have significant cytotoxic activity in all three cell lines; the in silico docking studies also reveal that compounds 22, 27 and 36 have good dock scores, binding affinities and binding energies towards human epidermal growth factor receptor 2. This is the first report to demonstrate theophylline hybrids containing 1,2,3-triazoles as potential anticancer agents.

Alpha7 nicotinic acetylcholine receptors (nAChRs) have implications in the regulation of cognitive processes such as memory and attention and have been identified as a promising therapeutic target for the treatment of the cognitive deficits associated with schizophrenia and Alzheimer's disease (AD). Structure affinity relationship studies of the previously described α7 agonist SEN12333 (8), have resulted in the identification of compound 45, a potent and selective agonist of the α7 nAChR with enhanced affinity and improved physicochemical properties over the parent compound (SEN12333, 8).

The synthesis (and full spectroscopic and crystallographic characterization) of new classes of bioorganometallic Ir- and Rh-complexes having β-lactam containing ligands has been achieved in three steps starting from simple precursors. The procedure for preparing these bioorganometallic compounds uses β-lactams having a phenylpyridyl moiety attached to the C4, N1 or C4 and N1 positions simultaneously, and a directed C-H metal-insertion, in the presence of (MCp*Cl2)2 (M = Ir, Rh). Enantiomerically pure 2-azetidinones can be transformed into diastereomeric (at the metal) mixtures of enantiopure metalla-2-azetidinones. Bimetallic 2-azetidinones are also accessible by this approach. The insertion of electron-poor alkynes into the M-C bond of the bioorganometallic complex occurs regioselectively and in excellent yields. Overall, the sequence imine-β-lactam-metalla-β-lactam is a versatile and efficient full methodology to prepare and functionalize unprecedented, novel Ir- and Rh-complexes having β-lactam containing ligands.
