Synthesis, characterization, in vitro cytotoxicity and anti-inflammatory activity of palladium(II) complexes with tertiary phosphines and heterocyclic thiolates: Crystal structure of [PdC28H19N8PS2]

The new four-coordinated mononuclear palladium(II) complexes 1-9 with chelating heterocyclic thiolates and tertiary phosphines with general formula [Pd(L)nCl(R?R2P)] (L = Pym2SH (pyrimidine-2-thiolate), Pur6SH (purine-6-thiolate), Py2SH (pyridine-2-thiolate), R3P = PPh3, P(o-tolyl)3, PPh2Cl), n = 1, 2) have been synthesized by the direct reaction of [PdCl2(R?R2P)2] with polyfunctional heterocyclic thiolates which display a wide variety of coordinations. These compounds were characterized by elemental analysis, FT-IR and multinuclear (1H, 13C and 31P) NMR. The X-ray diffraction study of non-ionic compound 5 showed that the thiolate acts as unidentate and that the chelating (-N,S) ligand adopts a slightly distorted square planar geometry around the palladium atom. In vitro the anti-inflammatory inhibition of compounds 1-9 was 10-15% greater than that of the standard drug Declofenac. Compounds 1 and 4 showed mostly a moderate to low cytotoxicity against seven human tumor cell lines whereas compound 3 was somewhat more active.

Discovery of LSZ102, a potent, orally bioavailable selective estrogen receptor degrader (SERD) for the treatment of estrogen receptor positive breast cancer

In breast cancer, estrogen receptor alpha (ERalpha) positive cancer accounts for approximately 74% of all diagnoses, and in these settings, it is a primary driver of cell proliferation. Treatment of ERalpha positive breast cancer has long relied on endocrine therapies such as selective estrogen receptor modulators, aromatase inhibitors, and selective estrogen receptor degraders (SERDs). The steroid-based anti-estrogen fulvestrant (5), the only approved SERD, is effective in patients who have not previously been treated with endocrine therapy as well as in patients who have progressed after receiving other endocrine therapies. Its efficacy, however, may be limited due to its poor physicochemical properties. We describe the design and synthesis of a series of potent benzothiophene-containing compounds that exhibit oral bioavailability and preclinical activity as SERDs. This article culminates in the identification of LSZ102 (10), a compound in clinical development for the treatment of ERalpha positive breast cancer.

Application of palladacycles in Heck type reactions

In the last 3 years, there have been tremendous developments in palladium catalytic systems for Heck type reactions. One of the successful approaches towards activation of less reactive substrates like aryl chlorides involves the use of palladacycles 1, 2 and 3 as catalyst precursors. This article describes the principles of these systems with an emphasis on our own work and features the ongoing literature discussion about possible mechanisms involving Pd(0)/Pd(II) or Pd(II)/Pd(IV) catalytic cycles for this class of catalyst.

Hydrophilic Pd0 complexes based on sugars for efficient suzuki-miyaura coupling in aqueous systems

Two classes of hydrophilic Pd0 complexes containing P,N and N,N sugar-based ligands were prepared and tested in the Suzuki-Miyaura cross-coupling reaction under environmentally friendly aqueous conditions. The best catalyst was tolerant towards different substrates, and its activity is comparable with the highest values reported so far for reactions in aqueous media [loading 0.0010-%, turnover frequency (TOF) 3.5-¡Á-104 h -1]. Sugar-derived hydrophilic Pd0 complexes are prepared and tested in aqueous Suzuki-Miyaura cross-coupling reactions. These conditions allow the green and sustainable synthesis of biaryls. The best catalysts achieve very good performances [turnover frequencies (TOFs) up to 3.5-¡Á-10 4 h-1; catalyst loadings down to 0.0010 mol-%], among the best reported for this reaction in aqueous conditions.

A robust first-pass protocol for the heck-mizoroki reaction

The Heck-Mizoroki (HM) reaction is one of the most widely used C-C bond-forming methods of contemporary synthesis. Notwithstanding this, these reactions frequently require significant optimization before efficient transformations can be obtained. We describe here the results of a study that aimed to establish a generic experimental protocol for HM reactions which enables acceptable yields from first-pass experiments. The methodology utilizes readily available stable catalysts and can be applied to a broad range of coupling partners.

Synthesis of Triazole Click Ligands for Suzuki-Miyaura Cross-Coupling of Aryl Chlorides

A series of new triazole ligands has been synthesized via copper-catalyzed cycloaddition reaction of readily available azides and alkynes. The synthesized compounds were characterized by FTIR, 1H and 13C NMR, and high-resolution mass spectra. The ligands provided excellent yields (up to 92%) in the palladium-catalyzed Suzuki-Miyaura cross coupling of unactivated aryl chlorides with phenylboronic acid. 1-Benzyl-4-(2,6-dimethoxyphenyl)-lH-1,2,3-triazole was found to be the most effective ligand due to the presence of electron-donating 2,6-dimethoxyphenyl substituent, which made it possible to develop a highly active ligand-catalyst system for the Suzuki reaction of aryl chlorides.

Luminescent infinite coordination polymer materials from metal-terpyridine ligation

A new class of infinite coordination polymers (CP) was synthesized using a tetrahedral tetrakis[4-(4?-phenyl-2,2?:6?,2??- terpyridine)phenyl]methane ligand as an organic node to direct the three-dimensional growth of the network and MII (M = Zn, Fe, Ni, and Ru) ions as inorganic linkers, an approach that is the opposite of the metal-as-a-node strategy used in the construction of metal-organic frameworks (MOFs). The unusual rod-like morphology of the resulting microporous materials can be tuned via solvents and reaction conditions. The covalent entrapment of a [Ru(tpy)2]2+ moiety in the skeleton of the 3D-network enables the Ru-CP to exhibit room-temperature luminescence.
