In order to better understand the effect of structure, halogen substitution, metal ions and ligand flexibility on antiproliferative activity, eight Cu(II) complexes and eight Pt(II) complexes were obtained of 2,4-X₁,X₂-6-((pyridine-2-ylmethylamino)methyl)phenol and 2,4-X₁,X₂-6-((pyridine-2-ylmethylamino)ethyl)phenol (where X is Cl, Br, or I) ligands. The compounds were characterized with various techniques, such as FT-IR, NMR, elemental anal. and single-crystal X-ray diffraction (SCXRD). The X-ray structures showed that ligand acts as a bidentate and tridentate donor in Cu(II) and Pt(II) complexes, resp. This difference in structures is due to the use or non-use of base in the preparation of complexes. Also, complexation of Cl₂-H₂L₁ with CuCl₂·2H₂O gives two different types of structures: polymer (Cl₂-H₂L₁-Cu^polymer) and dimer (Cl₂-H₂L₁-Cu^dimer), according to the crystal color. In addition, ¹H NMR spectrum for platinum complexes display two set of signals that can be attributed to the presence of two isomers in solution All complexes induced moderate to high reduction in A2780 and HCT116 cancer cell viability. However, only complexes bearing iodo- substituted in ligands exhibited significantly low cytotoxicity in normal fibroblasts when compared with cancer cell lines. The antiproliferative effect exhibited by I₂-H₂L₂-Cu complex in A2780 cell line was due to induction of cell death mechanisms, namely by apoptosis and autophagy. I₂-H₂L₂-Cu complex does not cause DNA cleavage but a slight delay in cell cycle was observed for the first 24 h of exposition. High cytotoxicity was related with the induction of intracellular ROS. This increase in intracellular ROS was not accompanied by destabilization of the mitochondrial membrane which is an indication that ROS are being triggered externally by I₂-H₂L₂-Cu complex and in agreement with an extrinsic apoptosis activation. I₂-H₂L₂-Cu complex has a pro-angiogenic effect, increasing the vascularization of the CAM in chicken embryos. This is also a very important characteristic in cancer treatment since the increased vascularization in tumors might facilitate the delivery of therapeutic drugs. Taken together, these results support the potential therapeutic of the I₂-H₂L₂-Cu complex.

The circadian clock is an intrinsic time-keeping system that controls daily rhythms in almost all living organisms on the earth. Daily rhythms are observed in various life phenomena, such as sleep-wake cycles, body temperature, blood pressure, and hormone secretion in animals, and stomatal movements and photosynthetic activity in plants. Therefore, controlling the circadian clock in a precise manner will make significant contributions in the elucidation of their mol. mechanisms, as well as to medicine and agriculture. Genetic and mol. biol. studies have made substantial progress in understanding of mol. clock mechanisms. For further investigation of the basic mechanisms as well as for therapeutic applications, small-mol. compounds will provide unique opportunities.

New thiazolyl derivatives (BT and TT) and their copper (II) complexes [Cu₂Cl₂(BT)₂] (Cu-BT) and [Cu₄ClO₂(TT)₂]PF₆·3.5H₂O (Cu-TT) were synthesized and characterized by elemental anal., ¹H NMR and ¹³C NMR, HRMS, X-ray diffraction, IR and UV-Vis spectroscopies. The crystal structure of Cu-BT shows the formation of a dinuclear complex where each copper(II) center is bonded to two thiazol N atoms, from different BT ligands, one deprotonated amide N atom, an O atom from the ester terminal groups and a chlorine atom. The structure found for Cu-TT is a pos. charged tetranuclear moiety containing two deprotonated TT ligands, a chlorine anion, two hydroxide anions acting as bridges between the copper centers and a water mol. The cytotoxic activity of both copper complexes was evaluated on metastatic breast cancer cell lines, characterized for its rapidly dividing behavior. Both, Cu-BT and Cu-TT, show higher cytotoxic activity against these tumor cells than free BT and TT and also than cisplatin. In addition, we found that both complexes interact with DNA. Consistently, they also show cytotoxicity against a rapidly dividing non-tumor cell line, although with higher IC_50, being such interaction and selectivity an indicator of the possible coexistence of more than one mechanism of action.

AlNajjar, Yasmeen T.;Gabr, Moustafa;ElHady, Ahmed K.;Salah, Mohamed;Wilms, Gerrit;Abadi, Ashraf H.;Becker, Walter;Abdel-Halim, Mohammad;Engel, Matthias research published 《 Discovery of novel 6-hydroxybenzothiazole urea derivatives as dual Dyrk1A/α-synuclein aggregation inhibitors with neuroprotective effects》, the research content is summarized as follows. A role of Dyrk1A in the progression of Down syndrome-related Alzheimer’s disease (AD) is well supported. However, the involvement of Dyrk1A in the pathogenesis of Parkinson’s disease (PD) was much less studied, and it is not clear whether it would be promising to test Dyrk1A inhibitors in relevant PD models. Herein, we modified our previously published 1-(6-hydroxybenzo[d]thiazol-2-yl)-3-phenylurea scaffold of Dyrk1A inhibitors to obtain a new series of analogs with higher selectivity for Dyrk1A on the one hand, but also with a novel, addnl. activity as inhibitors of α-synuclein (α-syn) aggregation, a major pathogenic hallmark of PD. The Ph acetamide derivative b27 displayed the highest potency against Dyrk1A with an IC₅₀ of 20 nM and high selectivity over closely related kinases. Furthermore, b27 was shown to successfully target intracellular Dyrk1A and to inhibit SF3B1 phosphorylation in HeLa cells with an IC₅₀ of 690 nM. In addition, two compounds among the Dyrk1A inhibitors, b1 and b20, also suppressed the aggregation of α-synuclein (α-syn) oligomers (with IC₅₀ values of 10.5μM and 7.8μM, resp.). Both compounds but not the Dyrk1A reference inhibitor harmine protected SH-SY5Y neuroblastoma cells against α-syn-induced cytotoxicity, with b20 exhibiting a higher neuroprotective effect. Compound b1 and harmine were more efficient in protecting SH-SY5Y cells against 6-hydroxydopamine-induced cell death, an effect that was previously correlated to Dyrk1A inactivation in cells but not yet verified using chem. inhibitors. The presented dual inhibitors exhibited a novel activity profile encouraging for further testing in neurodegenerative disease models.

The substituted phenethylamine analogs in this study are derivatives of N-(2-methoxybenzyl)-4-bromo-2,5-dimethoxyphenethylamine (25B-NBOMe) having the reverse substitution pattern for two aromatic rings. The nine regioisomeric compounds were prepared from the regioisomeric 2-, 3-, and 4- methoxyphenethylamines via N-reductive alkylation with the three regioisomeric 2,4,5-substituted bromodimethoxybenzaldehydes. The EI-MS spectra of these regioisomers gave two major bromine containing ions at m/z 229/231 (base peak) and 258/260 and two non-brominated fragments at m/z 91 and 121. The relative abundance of the m/z 91 was higher for the 2-methoxyphenethylamine substituted isomers and relative abundance of the m/z 121 fragment was higher in the 4-methoxy substituted isomers. The gas chromatog. separation for the regioisomeric methoxyphenethylamines of each bromodimethoxybenzyl aromatic ring substitution pattern showed 2-methoxyphenethylamine substituted isomer eluted first followed by the 3-substituted isomer and 4-methoxyphenethylamine substituted isomer was last to elute and the three bromodimethoxybenzyl regioisomers for the 2-methoxyphenethylamine subseries were resolved as the trifluoroacetamides. The EI-MS for the TFA derivatives of the 2-bromo-4,5-dimethoxybenzyl substituted isomer gave unique fragment ions resulting from displacement of bromine from the mol. ion.

Almaghrabi, Mohammed;Abiedalla, Younis;Dhanasakaran, Murali;DeRuiter, Jack;Randall Clark, C. research published 《 GC-MS and GC-IR of regioisomeric 4-N-bromodimethoxybenzyl derivatives of 3-trifluoromethylphenylpiperazine》, the research content is summarized as follows. The seven regioisomeric N-bromodimethoxybenzyl derivatives of 3-TFMPP were synthesized via reductive amination of the seven com. available bromodimethoxybenzaldehydes. The capillary GC elution profiles for these compounds generally follow the degree of methoxy group substituent crowding on the aromatic ring. The electron ionization mass spectra show a series of major fragment ions common to all seven regioisomeric compounds The base peak in the EI mass spectra for many of the seven regioisomers occurs at m/z 229 and is the result of contributions from two isobaric fragments, the trifluoromethylphenylpiperazine cation as well as the 79Br bromodimethoxybenzyl cation. Several low intensity ions are related to the specific regioisomeric substitution patterns for the bromodimethoxybenzyl moieties and provide some differentiation for this set of seven compounds These unique ions allow the seven compounds to be divided into sub-groups and in some cases allow specific isomer identification from only the EI-MS data. The 950 cm^-1 to 550 cm^-1 lower portion of the fingerprint region in the vapor phase IR spectra can be used to identify each of the bromodimethoxybenzyl regioisomers after EI-MS fragmentation patterns provide focus on the individual structural sub-groups of compounds in this study.
