Abstract
A less-studied halogen-free variation of the Hirao reaction involving the coupling of arylboronic acids with >P(O)H reagents, such as diarylphosphine oxides, diethyl phosphite, and ethyl phenyl-H-phosphinate, was investigated in detail using Pd(OAc)2 as the catalyst precursor and applying some excess of the P-reagent to supply the ligand via its trivalent tautomeric (>P-OH) form. The optimum conditions (1.2 equiv of the P-reagent, 135-150 °C, and air) were explored for the synthesis of diaryl-phenylphosphine oxides, aryl-diphenylphosphine oxides, diethyl arylphosphonates, ethyl diphenylphosphinate, and two bisphosphinoyl derivatives. In the reaction of 4-chlorophenyl- or 3-chlorophenylboronic acid with Ph2P(O)H, triphenylphosphine oxide was also formed as a byproduct. Theoretical calculations suggested that the catalytic cycle of the P-C coupling of PhB(OH)2 with Ph2P(O)H is different from that of the usual cross-coupling reactions. It comprises the addition of a phenyl anion and then the tautomeric form >P-OH of the >P(O)H reagent to the Pd2+ catalyst complex. This is then followed by reductive elimination affording Ph3PO that is accompanied with the conversion of Pd2+ to Pd0. There is a need for a subsequent stoichiometric oxidation of Pd(0) by molecular oxygen. The spontaneous formation of the self-assembling ligands around the Pd2+ center from the >P(O)H reactant plays a crucial role in the mechanism and promotes the efficiency of the catalyst.

Abstract
Novel hybrids of pyridazine-pyrazoline were synthesized aiming to develop new antiproliferative candidates. All compounds were submitted to the National Cancer Institute (NCI), USA, and many were proved to have significant antiproliferative activity. In addition, in vitro studies of the epidermal growth factor receptor (EGFR) inhibition showed that compounds IXn, IXg, IXb and IXl exhibited excellent inhibitory effect (IC50 = 0.65, 0.75, 0.82 and 0.84 μM, respectively) compared to Erlotinib (IC50 = 0.95 μM). The mechanistic effectiveness in cell cycle progression, apoptotic induction and gene regulation were assessed for the promising compounds IXg and IXn due to their significant EGFR inhibition. Flow cytometeric analysis indicated that compounds IXg and IXn result in increased cell numbers in phase G2/M, suggesting cell cycle arrest in phase G2/M in UO-31cells. Furthermore, real time PCR assay illustrated that compounds IXg and IXn elevated Bax/Bcl2 ratio which confirmed the mechanistic pathway of them. Moreover, the apoptotic induction of UO-31 renal cancer cells was enhanced effectively through activation of caspase-3 by compounds IXg and IXn. On the other hand, molecular docking study was performed to investigate binding mode of interaction of compounds with EGFR-PK in the active site with the aim of rationalizing its promising inhibitory activity. Finally, based on the aforementioned findings, compounds IXg and IXn could be considered as effective apoptosis modulators and promising leads for future development of new anti-renal cancer agents.

Abstract
Presented work describes the first approach for the biocatalytic resolution of racemic mixtures of heterophosphonate derivative. Penicillium funiculosum and Rhodotorula mucilaginosa were successfully applied for the biological conversion of racemic mixture of 1-amino-1-(3'-pyridyl)methylphosphonic acid 3. Both microorganisms carried out the kinetically driven process leading to conversion of one from the substrate enantiomers, leaving the second one unreacted. Application of R. mucilaginosa allowed obtaining pure enantiomer of the substrate (yield 100%, e.e 100% - unreacted isomer) after 24 h of biotransformation of 3 in the laboratory scale process (Method E), applying biocatalyst pre-treatment step - 24 h of starvation. In case of other biocatalyst, application of whole cells of P. funiculosum in laboratory scale process, also resulted in conversion of the racemic mixture of substrate 3via oxidative deamination into ketone derivative, which was then bioreduced (second step of the process) into 1-hydroxy-1-(3'-pyridyl)methylphosphonic acid 4. This time two products were isolated: unreacted substrate and hydroxy compound 4. Conversion degree ranged from 30% (standard procedure, method A) to even 70% (with extra addition of sodium pyruvate - method B2). However, in this case, bioconversion was not enantioselective - products: amino- and hydroxyderivative were obtained as racemic mixtures. Both biocatalysts were also tested towards the scaling so other biocatalytic procedures were introduced - with immobilized fungal mycelium. In case of Rhodotorula mucilaginosa this approach failed (data not shown) but Penicillium funiculosum turned out to be active and also selective. Thus, application of this biocatalyst in the half-preparative scale, continuous-flow bioprocess (Method C2) resulted in the obtaining of pure S-3 (100% e.e.) isomer with the 100% of conversion degree, without any side products. Recorded NMR spectra allowed confirming the reaction progress and its selectivity and also postulating possible mechanism of conversion.

Abstract
Many previous works have demonstrated that acetylcholinesterase (AChE) was enantioselectively inhibited by chiral organophosphorus insecticides (OPs) and that a significant difference in reactivation existed for AChE inactivated by (1R)- versus (1S,3S)-stereoisomers of isomalathion. It had been known that α-naphthyl acetate esterase (ANAE), an enzyme which might play an essential role in the growth of plants and the defense of plants against environmental stress by regulating the concentration of hormones in plants, can be inhibited by OPs. However, it was unknown whether interaction of ANAE with chiral OPs was enantioselective. The present work investigated the inhibition kinetics and spontaneous reactivation of ANAE inactivated by enantiomers of malaoxon, isomalathion, and methamidophos. The order of inhibition potency is (R) > (S) for malaoxon, (1R,3R) > (1R,3S) > (1S,3R) > (1S,3S) for isomalathion, and (S) > (R) for methamidophos according to bimolecular rate constants of inhibition (ki), which is consistent with the order observed in the enantioselective inhibition of AChE by malaoxon, isomalathion, and methamidophos. The difference in spontaneous reactivation of AChE inactivated between (1R)- and (1S,3S)-isomers of isomalathion is conserved for ANAE. The observations indicated ANAE and AChE have similar selective inhibition kinetics and postinhibitory reactions in reaction with chiral OPs.
