Cytotoxicity and Structural Analyses of 2,2?-Bipyridine-, 4,4?-Dimethyl-2,2?-bipyridine- and 2-(2?-Pyridyl)quinoxalineplatinum(II) Complexes

Platinum anticancer complexes incorporating 2,2?-bipyridine (bpy), 4,4?-dimethyl-2,2?-bipyridine (44Me2bpy) or 2-(2?-pyridyl)quinoxaline (2pq) as polyaromatic ligands and the S,S or R,R isomer of 1,2-diaminocyclohexane as ancillary ligands in the form [Pt(PL)(AL)]2+ have been synthesised and characterised. X-ray diffraction was used to elucidate the structure and stacking behaviour of the complexes, revealing interesting properties that may impact their biological activity. Pulsed gradient spin-echo NMR experiments elucidated the aggregation behaviour of these complexes in solution. The cytotoxicity of each complex was assessed against the L1210 murine leukaemia, HT29 human colon carcinoma and U87 human glioblastoma cell lines and compared to other complexes within this class. The complexes incorporating 44Me2bpy were found to be the most potent at inhibiting cell growth with IC50 values for the S,S isomer (0.13-0.5 muM) less than that for cisplatin (0.36-11 muM), oxaliplatin (0.9-1.8 muM) or carboplatin (>50 muM). Most complexes were found to be very effective against HT29 colon carcinoma cells.

The first catalytic, enantioselective aza-Henry reaction of an unactivated cyclic imine

The aza-Henry reaction is an efficient route to important chiral, vicinal diamines. Reports of the asymmetric version typically use electron-deficient acyclic imines. We report the first example of a catalytic, asymmetric aza-Henry reaction on an unfunctionalized cyclic imine that gives access to enantiopure diamine derivatives under experimentally straightforward conditions. The stereocentre is established through the initial nitromethane addition to the imine. The scalemic intermediate may be trapped through acylation, then crystallized. Copyright

Manganese-salen catalyzed oxidative benzylic chlorination

Abstract: Metalloporphyrins are well-known to serve as the model for mimicking reactivities exhibited by cytochrome P450 hydroxylase. Recent developments on selective C?H halogenation using Mn-porphyrins provided the way for understanding the reactivity as well as mechanism of different halogenase enzymes. In this report, we demonstrated a method for benzylic C?H chlorination using easily prepared Mn(salen) complex as the catalyst, which shows a complementary reactivity of Mn-porphyrins. Here, NaOCl has been used as a chlorinating source as well as the oxidant. Efforts towards understanding the mechanism suggested the formation of the high-valent Mn(V)=O species which is believed to be the key intermediate to conduct this transformation. Graphical abstract: SYNOPSIS Mn(salen)-catalyzed selective benzylic chlorination protocol has been developed using aqueous NaOCl solution. Reactions proceeded efficiently at room temperature and displayed good functional group tolerance. The mechanistic investigation demonstrated that Mn (V) = O species is likely to be the key intermediate which is responsible to generate benzylic radical. EPR and ESI-MS studies confirmed the in situ formation of Mn(IV)-species.[Figure not available: see fulltext.].

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: chiral-catalyst, you can also check out more blogs about21436-03-3

Enantioselective Synthesis of Planar-Chiral 1, n -Dioxa[ n ]paracyclophane-Based Phosphites and Their Application as Chiral Ligands

Various planar-chiral 1,n-dioxa[n]paracyclophanes possessing a phenolic hydroxyl group have been synthesized via enantioselective ortho-lithiation. Subsequent reaction with 2,2?-biarylene phosphorochloridites gave a new family of chiral phosphites. These phosphites were then used as chiral ligands in the enantioselective palladium-catalyzed allylic alkylation of dimethyl malonate with (E)-1,3-diphenylallyl acetate and the rhodium-catalyzed 1,4-addition of phenylboronic acid to cyclohex-2-enone.

Nano-zinc coordination with the ligands of carboplatin, oxaliplatin and nedaplatin. Synthesis, characterization and biological properties

The replacement of platinum in carboplatin, oxaliplatin and nedaplatin by zinc metal (in bulk and nano-scalled) produces biologically active compounds with increased solubility in water. We compared, in this work, three synthesized zinc-complexes from the ligands of platinum-anticancer drugs. The structural characterization of the products has been determined on the basis of their atomic absorption spectroscopy, elemental analysis, FT-IR, 1H and 13C NMR spectra. The crystalline structure and morphology of the products have been shown by XRD and SEM techniques. The antibacterial activities of the complexes have been examined through the growth inhibitory zone and minimal inhibitory concentrations.
