Structure-taste relationships for disubstituted phenylsulfamate tastants using classification and regression tree (CART) analysis

Forty-two new disubstituted phenylsulfamates have been synthesized, and 30 of these have been combined with 40 already available from earlier work to create a training database of 70 compounds. On the basis of panel taste data these were divided into three categories, N (nonsweet), N/S (nonsweet/sweet), and (S) sweet, and a “sweetness value” or weighting was also calculated for each compound. Using these 70 compounds as a training set and a series of nine predictors derived from Corey-Pauling-Koltun (CPK) models, calculated from the PC SPARTAN PRO program and Hammett sigma values taken from the literature, a classification and regression tree analysis (CART) was carried out leading to a regression tree that correctly classified 62 of the 70 compounds (89% overall correct classification). The tree’s predictive ability varies for the different taste categories, and for nonsweet compounds it is virtually 100%; for nonsweet/sweet compounds it is 66%, and for sweet compounds it is ?75%. This tree correctly predicted taste categories for 10 compounds from a test set of 12 randomly selected from among the 42 new compounds (83% correct classification). Therefore, it can be used with a good degree of confidence to predict the tastes of disubstituted phenylsulfamates. For the design of new sweeteners, appropriate values or ranges of the descriptors are derived.

Synthesis and evaluation of new quinazolin-4(3H)-one derivatives as potent antibacterial agents against multidrug resistant Staphylococcus aureus and Mycobacterium tuberculosis

Staphylococcus aureus and Mycobacterium tuberculosis are major causative agents responsible for serious nosocomial and community-acquired infections impacting healthcare systems globally. Over several decades, these pathogens have developed resistance to multiple antibiotics significantly affecting morbidity and mortality. Thus, these recalcitrant pathogens are amongst the most formidable microbial pathogens for which international healthcare agencies have mandated active identification and development of new antibacterial agents for chemotherapeutic intervention. In our present work, a series of new quinazolin-4(3H)-one derivatives were designed, synthesized and evaluated for their antibacterial activity against ESKAP pathogens and pathogenic mycobacteria. The experiments revealed that 4’c, 4’e, 4’f and 4’h displayed selective and potent inhibitory activity against Staphylococcus aureus with MIC values ranging from 0.03-0.25 mug/mL. Furthermore, compounds 4’c and 4’e were found to be benign to Vero cells (CC50 = >5 mug/mL) and displayed promising selectivity index (SI) > 167 and > 83.4 respectively. Additionally, 4’c and 4’e demonstrated equipotent MIC against multiple drug-resistant strains of S. aureus including VRSA, concentration dependent bactericidal activity against S. aureus and synergized with FDA approved drugs. Moreover, compound 4?c exhibited more potent activity in reducing the biofilm and exhibited a PAE of ?2 h at 10X MIC which is comparable to levofloxacin and vancomycin. In vivo efficacy of 4’c in murine neutropenic thigh infection model revealed that 4’c caused a similar reduction in cfu as vancomycin. Gratifyingly, compounds 4d, 4e, 9a, 9b, 14a, 4’e and 4’f also exhibited anti-mycobacterial activity with MIC values in the range of 2-16 mug/mL. In addition, the compounds were found to be less toxic to Vero cells (CC50 = 12.5->100 mug/mL), thus displaying a favourable selectivity index. The interesting results obtained here suggest the potential utilization of these new quinazolin-4(3H)-one derivatives as promising antibacterial agents for treating MDR-Staphylococcal and mycobacterial infections.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 22013-33-8, help many people in the next few years.Computed Properties of C8H9NO2

Structure-activity relationship study of selective benzimidazole-based inhibitors of Cryptosporidium parvum IMPDH

Cryptosporidium parasites are important waterborne pathogens of both humans and animals. The Cryptosporidium parvum and Cryptosporidium hominis genomes indicate that the only route to guanine nucleotides is via inosine 5?-monophosphate dehydrogenase (IMPDH). Thus the inhibition of the parasite IMPDH presents a potential strategy for treating Cryptosporidium infections. A selective benzimidazole-based inhibitor of C. parvum IMPDH (CpIMPDH) was previously identified in a high throughput screen. Here we report a structure-activity relationship study of benzimidazole-based compounds that resulted in potent and selective inhibitors of CpIMPDH. Several compounds display potent antiparasitic activity in vitro.

Rapid access to C3- and Cs-symmetric AAT organogelators via ring opening of a common benzotrifuranone precursor

Presented is a rapid and general approach to functionalised 1-aza-adamantanetrione (AAT) donor-sigma-acceptor molecules from a phloroglucinol-derived trilactone, benzotrifuranone (BTF). Ten C 3-symmetric AATs bearing diverse aryl amide substituents are accessed in two synthetic steps: (1) the exhaustive ring opening of BTF with aromatic amine nucleophiles (performed in up to 91% yield) and (2) cyclisation with hexamethylenetetramine (performed in up to 75% yield). Additionally, stepwise ring opening of BTF allows synthesis of phloroglucinol intermediates with two unique aryl amide substituents and ultimately Cs-symmetric AATs. Of the novel AATs prepared, three (including the Cs-symmetric hybrid) are effective gelators of chlorinated solvents (critical gelation concentration (CGC)=0.2-0.4 wt%) and one, with naphthyl substituents, forms translucent gels from aromatic solvents (CGC0 ? 3 wt%). The combination of AATs with moderately electron-poor and electron-rich aromatic substituents results in functional complementarity and gelation at concentrations below what is required for the individual components. Electron microscopy of the gel morphologies shows high aspect ratio fibres underlying the gel network superstructures in most cases. Polarised optical microscopy has allowed imaging of representative native organogel phases, and reveals striking morphology differences between gels that also share different optical and/or thermal stability properties.

Room temperature N-heterocyclic carbene manganese catalyzed selective N-alkylation of anilines with alcohols

The first example of room temperature non-noble metal homogeneous system catalyzed selective N-alkylation of anilines with alcohols by a bis-NHC manganese complex is presented. This system was applied to a large range of alcohols and anilines, including biologically relevant motifs and challenging methanol. Experimental and computational studies suggest an outer-sphere mechanism for this NHC-Mn system.

Quinazoline-based multi-tyrosine kinase inhibitors: Synthesis, modeling, antitumor and antiangiogenic properties

In this work the synthesis and the biological evaluation of some novel anilinoquinazoline derivatives carrying modifications in the quinazoline scaffold and in the aniline moiety were reported. Preliminary cytotoxicity studies identified three derivatives, carrying dioxygenated rings fused on the quinazoline portion and the biphenylamino substituent as aniline portion, as the most effective compounds. Further investigations revealed that these compounds exhibited antiproliferative activity on a wide panel of human tumor cell lines through the inhibition of both receptor and nonreceptor TKs. Furthermore, the compound bearing the dioxolane nucleus was also able to inhibit in vivo tumor growth. Molecular modeling of these compounds into kinase domain suggested that the phenyl group allows favorable interaction energies with the target proteins: this feature is favored by fused dioxygenated ring at the 6,7 positions, whereas free rotating functions do not allow the correct placement of the molecule, thus impairing the inhibitory potency. Finally, the biphenylamino derivatives, at noncytotoxic concentrations, acted as antiangiogenic agents both in in vitro and in vivo assays.

Synthesis and identification of [1,3,5]triazine-pyridine biheteroaryl as a novel series of potent cyclin-dependent kinase inhibitors

On the basis of previous studies, we identified pyrazine-pyridine A as a potent vascular endothelial growth factor inhibitor and pyrimidine-pyridine B as a moderately potent cyclin dependent kinase (CDK) inhibitor. A proposed combination of CGP-60474 and compound B led to the discovery of [1,3,5]triazine-pyridine as a new series of potent CDK inhibitors. Palladium-catalyzed C-C bond formation reactions, particularly the Negishi coupling reaction, were used to assemble various triazine-heteroaryl analogues effectively. Among them, compound 20 displayed high inhibitory potency at CDKl (IC50 = 0.021 muM), CDK2, and CDK5 and submicromolar potency at CDK4, CDK6, and CDK7. Compound 20 also displayed high potency at GSK-3beta. It demonstrated potent antiproliferative activity on various tumor cell lines, including HeLa, HCT-116, U937, and A375. When 20 was administered intraperitoneally at 150 and 125 mg/kg to nude mice bearing human A375 xenografts, the compound produced a significant survival increase. Molecular docking studies were conducted in an attempt to enhance the understanding of the observed structure-activity relationship.

Guanidine and 2-aminoimidazoline aromatic derivatives as alpha2-adrenoceptor antagonists, 1: Toward new antidepressants with heteroatomic linkers

The efficient preparation and pharmacological characterization of different families of (bis)guanidine and (bis)2-aminoimidazoline derivatives (“twin” and “half” molecules) as potential alpha2-adrenoceptor antagonists for the treatment of depression is presented. The affinity toward the alpha2-adrenoceptor of all the compounds prepared was measured in vitro in human brain tissue. Additionally, the activity as agonist or antagonist of those compounds with a pKi larger than 7 was determined in functional [35S]GTPgammaS binding assays in human brain tissue. Finally, the activity of the most promising compounds was confirmed by means of in vivo microdialysis experiments in rats. Compounds 1, 2b, 3b, 12b, 13b, 17b, 18b, 22b, 25b, 26b, 28b, and 30 showed a good affinity toward the alpha2-ARs. In general, the 2-aminoimidazoline derivatives displayed higher affinities than their guanidine analogues. Finally and most importantly, compounds 18b and 26b showed antagonistic properties over alpha2-ARs not only in vitro [ 35S]GTPgammaS binding but also in vivo microdialysis experiments. Moreover, both compounds have shown to be able to cross the blood-brain barrier and, therefore, they can be considered as potential antidepressants.
