Thirty-four seco-3’R,4’R-disubstituted-2′,2′-dimethyldihydropyrano[2,3-f]chromone (seco-DSP) derivatives were designed, synthesized and evaluated for chemo-reversal activity when combined with paclitaxel or vincristine in P-gp overexpressing A2780/T and KB-VIN drug-resistant cancer cell lines. Most of the compounds displayed moderate to significant MDR reversal activities. Compound 7e showed the most potent chemo-sensitization activity with more than 1471 reversal ratio at a concentration of 10 mu M, which was higher than verapamil (VRP) (212-fold). Unexpectedly the newly synthesized compounds did not show chemosensitization activities in a non-P-gp overexpressing cisplatin resistant human ovarian cancer cell line (A2780/CDDP), implying that the MDR reversal effects might be associated with P-gp overexpression. Moreover, the compounds did not exhibit significant anti-proliferative activities against non-tumorigenic cell lines (HUVEC, HOSEC and T29) compared to VRP at the tested concentration and might be safer than VRP. In preliminary pharmacological mechanism studies, the compounds increased accumulation of DOX and promoted P-gp ATPase activity in A2780/T cell lines. Western blot analysis indicated they did not affect the expression level of P-gp in the tested MDR cell lines. Thus, further studies on these seco-DSP derivatives are merited with the goal of developing a desirable chemosensitizer drug candidate. (C) 2020 Elsevier Masson SAS. All rights reserved.

Co-crystallizations can be utilized for generating new solid forms of a target substance in order to alter or enhance some specific bulk physical property. Generally, selection of the co-former (the necessary partner for the target molecule) is based on existing structural information about molecular recognition events involving complementary functional groups, and extensive experimental screening methods. In this study, we utilize structure-informatics in an attempt to predict if two different molecules will form a co-crystal or not. Our study is based on hydrogen-bond propensity (HBP), and the key premise of our approach rests on whether target-co-former interactions are more likely to take place than either target-target or co-formerco-former hydrogen bonds. We examined six different target molecules in combination with 25 possible co-formers each and used the HBP protocol for predicting if a co-crystal would form or not. The predictions were then compared with results from an experimental co-crystal screen of the 150 different combinations. The correct outcome was successfully predicted 92-95% of the time which shows that for this series of small molecules, HBP is a very reliable indicator for determining if a co-crystal will form between a target molecule and a particular co-former.

I found the field of Pharmacology & Pharmacy; Chemistry very interesting. Saw the article New 2,4-disubstituted-2-thiopyrimidines as VEGFR-2 inhibitors: Design, synthesis, and biological evaluation published in 2019.0. Safety of 2,5-Dimethoxybenzaldehyde, Reprint Addresses Abdel-Mohsen, HT (corresponding author), Natl Res Ctr, Dept Chem Nat & Microbial Prod, Div Pharmaceut & Drug Ind Res, El Buhouth St,POB 12622, Cairo, Egypt..

A new series of 2,4-disubstituted-2-thiopyrimidines 6a-t, 9a, and 9b was efficiently designed and synthesized as antiangiogenic and cytotoxic agents. Compounds 6j, 6l, and 6d showed IC50 values of 1.23, 3.78, and 3.84 mu M, respectively, against the vascular endothelial growth factor receptor-2 (VEGFR-2). Most of the synthesized 2-thiouracils showed antiproliferative activity against the HepG2 cell line (hepatocellular carcinoma) in the micromolar range, for instance, 9b, 6l, 6m, 6n, and 6j displayed IC50 = 7.92, 8.35, 8.51, 9.59, and 13.06 mu M, respectively, relative to sorafenib (III; IC50 = 10.99 mu M). Also, compounds 6j, 9a, 6m, and 6s (IC50 = 15.21, 16.96, 17.68, and 18.15 mu M, respectively) are the most potent compounds against the UO-31 cell line. Further evaluation of the effect of the synthesized candidates on VEGFR-2 in the HepG2 cell line demonstrated that compounds 6j and 6l exhibit VEGFR-2 inhibitory activity of 87% and 84%, respectively, relative to sorafenib (III; 92%). In silico docking of the synthesized hits into the binding site of VEGFR-2 showed their ability to perform the main binding interactions with the key amino acids in the binding site. Studying the in silico predicted ADME (absorption, distribution, metabolism, and excretion) parameters for the synthesized thiouracils demonstrated that they have favorable pharmacokinetic and drug-likeness properties. These results demonstrate that the 2,4-disubstituted thiouracils 6 and 9 have not only favorable antiangiogenic and antiproliferative activity but also satisfy the criteria required for the development of orally bioavailable drugs. Consequently, they represent a biologically active scaffold that should be further optimized for future discovery of potential hits.

A water-mediated MCR strategy has been developed for the synthesis of donor (D)-acceptor(A) type hydrazinyl thiazolyl coumarins (HTCs) (4) in excellent isolated yields (90-98%) from a three component reaction of aromatic aldehydes/ketones (1), thiosemicarbazide (2) and 3-(2-bromoacetyl)-2H-chromen-2-one (3) catalyzed by an environmentally compatible montmorillonite (MMT) K10 clay at RT for 20-40 min. The present MCR strategy has several advantages that include its wide-spread substrate scope, eco-compatibility, short reaction times and products that do not require chromatographic purification. Besides, the method is simple to perform, it is easy to construct C-N, C=N and C-S bonds in one pot and the reaction can be scaled up to a gram level. Moreover, the catalyst can be reused 7 times without significant change of activity. The photophysical properties of the synthesized D-A type HTCs are also studied and it was noticed that the fluorescence properties can be varied with the position of electron donating group on the aromatic ring of aldehyde/ketone of HTCs. Most of the compounds exhibited bright fluorescence in chloroform (1.0 x 10(-5) M) with emission maxima ranging from 409 to 511 nm and large Stokes shifts. Further, the HOMO and LUMO energy levels of the HTCs are found in the range from -5.65 eV to -5.22 eV and -2.67 eV to -2.17 eV, respectively, and in good agreement with the reported hole transporting materials.

Twenty-five seco-4-methyl-DCK derivatives were designed, synthesized and evaluated for chemoreversal activity when combined with paclitaxel or vincristine in two drug-resistant cancer cell lines (A2780/T and KB-V) respectively. Most of the new compounds displayed moderate to significant MDR reversal activities in the P-gp overexpressing A2780/T and KB-V cells. Especially, compounds 7o and 7y showed the most potent chemosensitization activities with more than 496 and 735 reversal ratios at a concentration of 10 mu M. Unexpectedly the newly synthesized compounds did not show chemosensitization activities observed in a non-P-gp overexpressing cisplatin resistant human ovarian cancer cell line (A2780/CDDP), implying that the MDR reversal effects might be associated with P-gp overexpression. Moreover, these compounds did not exhibit significant antiproliferative activities against nontumorigenic cell lines (HUVEC, HOSEC and T29) compared to the positive control verapamil at the tested concentration, which suggested better safety than verapamil. The pharmacological actions of the compounds will be studied further to explore their merit for development as novel candidates to overcome P-gp mediated MDR cancer.

Imidazoline-based small molecule inhibitors of p53-MDM2 interaction intended for the treatment of p53 wild-type tumors are the promising structures for design of anticancer drugs. Based on fragment approach we have investigated a key role of substituents in cis-imidazoline core for biological activity of nutlin family compounds. Although the necessity of the substituents in the phenyl rings of cis-imidazoline has been shown, there are no studies in which the replacements of a halogen by other substituents have been investigated. A series of simple cis-imidazoline derivatives containing halogen, hydroxy and alkoxy-substituents were synthesized. The biological activity of the compounds was studied using assays of cytotoxicity (MTT) and p53 level. It was found that the hydroxyl-derivatives were not cytotoxic whereas the alkoxy analogues were the same or more active as halogen-substituted compounds in cell viability test. The synthesized alkoxy derivatives induced an increase of p53 level and did not promote necrotic cell death in the concentration up to 40 mu M.
