Design, synthesis and biological evaluation of pyrimidine derivatives as novel CDK2 inhibitors that induce apoptosis and cell cycle arrest in breast cancer cells

Cyclin-dependent kinase 2 (CDK2) plays a key role in eukaryotic cell cycle progression which could facilitate the transition from G1 to S phase. The dysregulation of CDK2 is closely related to many cancers. CDK2 is utilized as one of the most studied kinase targets in oncology. In this article, 24 benzamide derivatives were designed, synthesized and investigated for the inhibition activity against CDK2. Our results revealed that the compound 25 is a potent CDK2 inhibitor exhibiting a broad spectrum anti-proliferative activity against several human breast cancer cells. Additionally, compound 25 could block cell cycle at G0 or G1 and induce significant apoptosis in MDA-MB-468 cells. These findings highlight a rationale for further development of CDK2 inhibitors to treat human breast cancer.

Polymeric bimetallic catalyst-promoted in-water dehydrative alkylation of ammonia and amines with alcohols

A dehydrative alkylation with three kinds of Ir/B heterobimetallic polymeric catalysts in water is reported. The polymeric heterobimetallic catalysts were readily prepared by ionic convolution of a poly(catechol borate) and iridium complexes. The N-alkylation of ammonia and amines with alcohols, as alkylating agents, was carried out with a heterogeneous catalyst (1 mol% Ir) at 100 C without the use of organic solvents under aerobic and aqueous conditions to afford the corresponding alkylated amines in high yield.

Thermal transformations of tris(2-thienyl)phosphine (PTh3) at low-valent ruthenium cluster centers: Part I. Carbon-hydrogen, carbon-phosphorus and carbon-sulfur bond activation yielding Ru3(CO)8L{mu-Th2P(C4H2S)}(mu-H) (L = CO, PTh3), Ru3(CO)7(mu-PTh2)2(mu3-eta2-C4H2S), Ru4(CO)9(mu-CO)2(mu4-eta2-C4H2S)(mu4-PTh) and Ru5(CO)11(mu-PTh2)(mu4-eta4-C4H3)(mu4-S)

Reaction of Ru3(CO)12 with tris(2-thienyl)phosphine (PTh3) in CH2Cl2 at room temperature or in THF in the presence of a catalytic amount of Na[Ph2CO] furnishes the carbonyl substitution products Ru3(CO)11(PTh3) (1), Ru3(CO)10(PTh3)2 (2), and Ru3(CO)9(PTh3)3 (3). Heating 1 in toluene affords the cyclometalated cluster Ru3(CO)9{mu-Th2P(C4H2S)}(mu-H) (4) resulting from carbonyl loss and carbon-hydrogen bond activation, and both 4 and the substituted derivative Ru3(CO)8{mu-Th2P(C4H2S)}(PTh3)(mu-H) (5) resulted from the direct reaction of Ru3(CO)12 and PTh3 at 110 C in toluene. Interestingly, thermolysis of 2 in benzene at 80 C affords 5 together with phosphido-bridged Ru3(CO)7(mu-PTh2)2(mu3-eta2-C4H2S) (6) resulting from both phosphorus-carbon and carbon-hydrogen bond activation of coordinated PTh3 ligand(s). Cluster 6 is the only product of the thermolysis of 2 in toluene. Heating cyclometalated 4 with Ru3(CO)12 in toluene at 110 C yielded the tetranuclear phosphinidine cluster, Ru4(CO)9(mu-CO)2(mu4-eta2-C4H2S)(mu4-PTh) (7), resulting from carbon-phosphorus bond scission, together with the pentaruthenium sulfide cluster, Ru5(CO)11(mu-PTh2)(mu4-eta4-C4H3)(mu4-S) (8), in which sulfur is extruded from a thiophene ring. All the new compounds were characterized by elemental analysis, mass spectrometry, IR and NMR spectroscopy, and by single crystal X-ray diffraction analysis in case of clusters 4, 6, 7, and 8. Cluster 4 consists of a triangular ruthenium framework containing a mu3-Th2P(C4H2S) ligand, while 6 consists of a ruthenium triangle containing eta2-mu3-thiophyne ligand and two edge-bridging PTh2 ligands. Cluster 7 exhibits a distorted square arrangement of ruthenium atoms that are capped on one side by a mu4-phosphinidene ligand and on the other by a 4e donating mu4-eta2-C4H2S ligand. The structure of 8 represents a rare example of a pentaruthenium wing-tip bridged-butterfly skeleton capped by mu4-S and mu4-eta4-C4H3 ligands. The compounds 4, 6, 7, and 8 have been examined by density functional theory (DFT), and the lowest energy structure computed coincides with the X-ray diffraction structure. The hemilabile nature of the activated thienyl ligand in 4 and 6 has also been computationally investigated.

Natural superabsorbent plastic materials based on a functionalized soy protein

A natural superabsorbent polymer (SAP) material based on an acylated soy protein was studied as a green alternative to non-biodegradable SAP. In order to obtain the natural SAPs, different amounts of succinic anhydride were used as acylating agent. Once the functionalized protein was obtained, it was mixed thoroughly with glycerol and then molded through a lab-scale injection molding device. Water uptake of samples obtained reached values much higher than those based on unacylated protein. Moreover, a greater extent of the acylation reaction led to higher water uptake values for the corresponding SAPs, probably related to their higher hydrophilic character. Water imbibing capacity measurements and thermogravimetrical analysis (TGA) seemed to confirm this. The presence of larger porous regions in acylated samples observed in SEM images could also play a role in their higher water uptake values. Furthermore, an increase in the extent of acylation reaction led to plastics with lower Young’s modulus and higher extensibility.

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.Synthetic Route of 52722-86-8, you can also check out more blogs about52722-86-8

Simultaneous detection and removal of cobalt ions from aqueous solution by modified chitosan beads

Abstract: In this paper, we modified chitosan beads in order to simultaneously detect and adsorb Co2+ from aqueous solution. Firstly, 4-(5-chloro-2-pyridylazo)-1,3-phenylenediamine (5-Cl-PADAB) was used as selective probe for Co2+ with color changing from yellow to pink, and the UV?Vis spectra showed that the lambdamax changed from 439 to 504?nm. Then a novel biomaterial was synthesized with 5-Cl-PADAB (metal indicator), chitosan (biosorbent) and EDTA anhydride (cross-linker and chelating agent). The analysis of Fourier transform infrared and energy-dispersive X-ray spectra proved that 5-Cl-PADAB and EDTA were successfully connected to chitosan. The modified chitosan bead was selective probe for Co2+ with a remarkable color change from white to pink, and the UV?Vis spectra showed that the lambdamax changed from 441 to 459?nm. The adsorption of cobalt ions onto the modified chitosan beads followed pseudo-second-order (R2?=?0.99) kinetics and the Langmuir isotherm model (R2?=?0.80). Comparing with chitosan beads, the qe of the modified one increased from 2.00 to 7.97?mg/g. The modified chitosan beads are promising biomaterial for simultaneous detection and removal of Co2+ from aqueous solution.
