Achieving NIR Emission for Donor-Acceptor Type Platinum(II) Complexes by Adjusting Coordination Position with Isomeric Ligands

Four platinum(II) complexes Pt-1, Pt-2, Pt-3, and Pt-4 with the isomeric donor-acceptor (D-A) conjugated ligand framework are designed and prepared, and their thermal, photophysical, and electrochemical characteristics investigated. Crystal structures for Pt-1 and Pt-4 are determined with single-crystal X-ray diffraction analysis, showing distorted and nonplanar geometry. Complex Pt-4 exhibits much greater distortion, attributed to the steric interactions between benzothiadiazole and naphthalene. Remarkably different photophysical, electrochemical, and electroluminescent properties are found for these platinum(II) complexes. Photoluminescence wavelengths of these complexes range from 590 to 800 nm with bandgaps of 1.7-2.0 eV. Coordination with [1,2,5]thiadiazolo[3,4-c]pyridine and triphenylamine can enhance D-A interactions, reducing the bandgap and producing near-infrared emission for Pt-3. Organic light-emitting devices (OLEDs) display electroluminescence with emission peaks at 626, 645, 826, and 571 nm, with maximum external quantum efficiencies of 0.13%, 0.04%, 0.49%, and 0.22% for Pt-1, Pt-2, Pt-3, and Pt-4 doped OLEDs, respectively. Thus, adjusting the coordination position with the isomeric conjugation framework ligand is an appropriate strategy to tune the light-emitting properties of platinum complexes in OLEDs.

Palladium(II)-Catalyzed One-Pot Syntheses of 9-(Pyridin-2-yl)-9H-carbazoles through a Tandem C-H Activation/C-X (X=C or N) Formation Process

A new one-pot synthesis of 9-(pyridin-2-yl)-9H-carbazoles through the simultaneous C-H activation and palladium(II)-catalyzed cross-coupling of N-phenylpyridin-2-amines with potassium aryltrifluoroborates is presented. Silver acetate and 1,4-dioxane proved to be the best oxidant and solvent, respectively. The product yields fluctuated from modest to excellent and the reaction showed sufficient functional group tolerance. p-Benzoquinone served as an important ligand for the transmetalation and reductive elimination steps in the catalytic process. The kinetic isotope effects (kH/kD) for the first and second C-H activation/C-C or C-N formation steps were measured as 2.14 and 1.18, respectively. Finally, a rational catalytic mechanism is presented based on all experimental evidence. Thrown together to perform: A variety of N-pyridylcarbazoles were synthesized through concurrent C-H activation/coupling of N-phenylpyridin-2-amines with potassium aryltrifluoroborates (see scheme; BQ=p-benzoquinone). The catalytic mechanism was elucidated by the examination of X-ray crystal structures of PdII intermediates and key products, as well as control experiments and kinetic isotope effect studies.

Revisiting tubercidin against kinetoplastid parasites: Aromatic substitutions at position 7 improve activity and reduce toxicity

The nucleoside antibiotic tubercidin displays strong activity against different target organisms, but it is notoriously toxic to mammalian cells. The effects of tubercidin against T. brucei parasites inspired us to synthesize several C7 substituted analogs for in vitro evaluation in order to find suitable hit compounds. C7 Deazaadenosines substituted with electron-poor phenyl groups were found to have micromolar activity against T. brucei in vitro. Replacement of the phenyl for a pyridine ring gave compound 13, with submicromolar potency and much-attenuated cytotoxicity compared to tubercidin. The veterinary pathogen T. congolense was equally affected by 13 in vitro. Transporter studies in T. b. brucei indicated that 13 is taken up efficiently by both the P1 and P2 adenosine transporters, making the occurrence of transporter-related resistance and cross-resistance with diamidine drugs such as diminazene aceturate and pentamidine as well as with melaminophenyl arsenicals unlikely. Evaluation of the in vitro metabolic stability of analog 13 indicated that this analog was significantly metabolized in mouse microsomal fractions, precluding further in vivo evaluation in mouse models of HAT.

Suzuki-Miyaura cross-coupling for efficient synthesis of aryl-substituted N-heteroarenes catalyzed by recyclable N-phenylpiperazine-Palladium(II) complex

Polystyrene supported N-phenylpiperazine-Pd(II) complex D was synthesized and characterized by various techniques, including Fourier transform infrared spectroscopy (FTIR), scanning electronmicroscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and thermal analysis (TG-DTA). This heterogeneous Pd(II) complex showed high catalytic efficiency for the Suzuki-Miyaura coupling of arylboronic acids with aryl bromides, aryl chlorides to give the corresponding 2-arylpyridines and heteroarenes. The coupled products were formed in excellent yields at low catalyst loadings under mild reaction conditions. Further, this heterogeneous catalyst showed excellent recyclability and reused for four cycles with no significant decrease in its activity.

A combination of 10 % CoCl2 and 20 % 2,2?-bipyridine ligands enables cross-coupling of functionalized primary and secondary alkylzinc reagents with various (hetero)aryl halides. Couplings with 1,3- and 1,4-substituted cycloalkylzinc reagents proceeded diastereoselectively leading to functionalized heterocycles with high diastereoselectivities of up to 98:2. Furthermore, alkynyl bromides react with primary and secondary alkylzinc reagents providing the alkylated alkynes.

Optimization of N-aryl-6-methoxy-1,2,3,4-tetrahydroquinolines as tubulin polymerization inhibitors

Thirteen new N-aryl 1,2,3,4-tetrahydroquinoline compounds (4a-f, 6a-c, and 8a-d) were synthesized and evaluated for antitumor activity and drug-like properties. Compound 4a exhibited high inhibitory potency with low nanomolar GI50 values of 16-20 nM in cellular assays, including excellent activity against the P-glycoprotein overexpressing cell line KBvin. Compound 4a inhibited colchicine binding to tubulin and tubulin assembly with an IC50 value of 0.85 muM, superior to the reference compound CA4 (1.2 muM) in the same assay. In addition, 4a also exhibited highly improved water solubility (75 mug/mL) and a suitable log P value (3.43) at pH 7.4. With a good balance between antitumor potency and drug-like properties, compound 4a could be a new potential drug candidate for further development. Current results on SAR studies and molecular modeling provided more insight about this class of compounds as tubulin polymerization inhibitors targeting the colchicine site.

A Pd(ii)/Mg-La mixed oxide catalyst for cyanation of aryl C-H bonds and tandem Suzuki-cyanation reactions

A palladium(ii)/magnesium-lanthanum mixed oxide (Pd(ii)/Mg-La) catalyst is a reusable catalyst for cyanation of aromatic C-H bonds by using the combination of NH4HCO3 and DMSO as the ”CN” source. Moderate to good yields of aromatic nitriles were obtained. An excellent regioselectivity was achieved using the present protocol. A tandem process involving Suzuki coupling followed by a cyanation reaction was also developed using the heterogeneous (Pd(ii)/Mg-La) catalyst. This cascade process resulted in the formation of aromatic nitrile from simple 2-halopyridine. The catalyst was recovered by centrifugation and reused for three consecutive cycles with nearly consistent activity and selectivity. This journal is
