The organoactinide-catalyzed (Cp*₂ThMe₂) hydroborated reduction of a wide range of tertiary, secondary, and primary amides to the corresponding amines/amine-borane adducts via deoxygenation of the amides is reported herein. The catalytic reactions proceed under mild conditions with low catalyst loading and pinacolborane (HBpin) concentration in a selective fashion. Cp*₂ThMe₂ is capable of efficiently catalyzing the gram-scale reaction without a drop in efficiency. The amine-borane adducts are successfully converted into free amine products in high conversions, which increases the usefulness of this catalytic system. A plausible mechanism is proposed based on detailed kinetics, stoichiometric, and deuterium labeling studies.

Brun, Omar published the artcileOn-Resin Conjugation of Diene-Polyamides and Maleimides via Diels-Alder Cycloaddition, Product Details of C40H35N7O8, the publication is Journal of Organic Chemistry (2015), 80(12), 6093-6101, database is CAplus and MEDLINE.

The reaction between maleimides and resin-bound diene-polyamides (polyamides are represented by peptides and peptide nucleic acids or PNAs) allows the latter to be used in the preparation of conjugates. Conjugation takes place by reacting the insoluble, hydrophobic diene component either with water-soluble dienophiles or with dienophiles requiring mixtures of water and organic solvents. Exptl. conditions can be adjusted to furnish the target conjugate in good yield with no need of adding large excesses of soluble reagent. In case protected maleimides are used, maleimide deprotection and Diels-Alder cycloaddition can be simultaneously carried out to render conjugates with different linking positions. On-resin conjugation is followed by an acidic treatment that removes the polyamide protecting groups with no harm to the cycloadduct, in contrast with the unreacted diene that is indeed degraded under these conditions. Cycloadducts incorporating suitable functional groups can undergo subsequent addnl. conjugation reactions in solution to furnish double conjugates.

New tilomisole-based benzimidazothiazole derivatives were designed and synthesized in this work. Their anti-inflammatory activity was assessed through the in vivo carrageenan rat paw edema model, and the in vitro COX inhibition assay. Compounds 13, 20, 30, 40, 43, and 46 demonstrated values of inhibition of induced edema in the in vivo assay comparable to celecoxib. All the synthesized compounds expressed their activity on COX-2 enzyme more than COX-1, proving their advantageous selectivity. In addition, compounds 13, 16, 20, 25, and 46 displayed lower IC₅₀ values than celecoxib as a reference drug against COX-2 enzyme; having values of 0.09, 13.87, 32.28, 33.01, and 5.18 nM resp. vs 40.00 nM for celecoxib. Particularly, the most active compound (13) with its extreme potency (400 folds more potent than celecoxib) exhibited a notable high selectivity index (SI = 159.5). In silico studies, including ADMET prediction, compliance to Lipinski′s rule of five, and mol. docking into the active site of both COX isoenzymes were conducted for the synthesized compounds The results suggested that these compounds are good candidates for orally active drugs, and docking revealed higher number of interactions with COX-2 for 13 as the most active compound compared with COX-1 reflecting its advantageous selectivity and explaining its extreme potency.

Accumulating evidence indicates that leukotriene B4 (LTB4) via its receptors BLT1 and/or BLT2 (BLTRs) could have an important role in regulating infection, tumor progression, inflammation, and autoimmune diseases. In the present study, we showed that LTB4 not only augments cytotoxicity by NK cells but also induces their migration. We found that approx. 30% of fresh NK cells express BLT1, 36% express BLT2, and 15% coexpress both receptors.The use of selective BLTR antagonists indicated that BLT1 was involved in both LTB4-induced migration and cytotoxicity, whereas BLT2 was involved exclusively in NK cell migration, but only in response to higher concentrations of LTB4. BLT1 and BLT2 expression increased after activation of NK cells with IL-2 and IL-15.These changes of BLTR expression by cytokines were reflected in enhanced NK cell responses to LTB4. Our findings suggest that BLT1 and BLT2 play differential roles in LTB4-induced modulation of NK cell activity.

Abulkhair, Hamada S. published the artcileIn vivo- and in silico-driven identification of novel synthetic quinoxalines as anticonvulsants and AMPA inhibitors, Recommanded Product: 2-Chloroacetamide, the publication is Archiv der Pharmazie (Weinheim, Germany) (2021), 354(5), 2000449, database is CAplus and MEDLINE.

The lack of effective therapies for epileptic patients and the potentially harmful consequences of untreated seizure incidents have made epileptic disorders in humans a major health concern. Therefore, new and more potent anticonvulsant drugs are continually sought after, to combat epilepsy. On the basis of the pharmacophoric structural specifications of effective α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) antagonists with an efficient anticonvulsant activity, the present work reports the design and synthesis of two novel sets of quinoxaline derivatives The anticonvulsant activity of the synthesized compounds was evaluated in vivo according to the pentylenetetrazol-induced seizure protocol, and the results were compared with those of perampanel as a reference drug. Among the synthesized compounds, four showed promising activities with ED₅₀ values of 37.50, 23.02, 29.16, and 23.86 mg/kg. Docking studies of these compounds suggested that AMPA binding could be the mechanism of action of these derivatives Overall, the pharmacophore-based structural optimization, in vivo and in silico docking, and druglikeness studies indicated that the designed compounds could serve as promising candidates for the development of effective anticonvulsant agents with good pharmacokinetic profiles.

A series of cyano oximino sulfonate derivatives RS(O)2ON:C(CN)X (R = 4-CH₃C₆H₅, naphthalen-2-yl; X = C₆H₅, C₂H₅NH₂, NH₂, etc). were prepared from the reaction of arylsulfonyl chloride with different cyanoacetamide-based oximes ranging from the simplest unsubstituted amide to analogs containing N-Et (mimicking the Oxyma template), N-piperidinyl and N-morpholinyl chains. In addition, the cyano oximes, N-hydroxybenzimidoyl cyanide and N-hydroxy picolinimidoyl cyanide were also used in the synthesis of cyano oximino sulfonate derivatives The preliminary bioassays showed that some of the title compounds, such as (TsPipOx), (TsPhOX), (NpsPipOx) etc, showed anti-proliferation effect on the mouse fibroblast L929. The calculated IC₅₀-values were ranging between 36.5 μg/mL and 0.235 mg/mL. However the anti-proliferation effects seem to be cytostatic rather than cytotoxic. The compounds only minimize the growth activity without completely killing the cells.

Hassan, Aisha Y. published the artcilePotential antiviral and anticancer effect of imidazoles and bridgehead imidazoles generated by HPV-Induced cervical carcinomas via reactivating the P53/pRb pathway and inhibition of CA IX, Application of 2-Chloroacetamide, the publication is Journal of Molecular Structure (2021), 129865, database is CAplus.

Human papillomaviruses E6 and E7 oncoproteins are crucial to viral-induced cervical cancers and targeting E6/E7 leads to safer and better treatment for cervical cancer. Hence, a simple and green solvent-free protocol was applied for the synthesis of novel imidazoles e.g., I, and bridgehead imidazoles (purine analogs), e.g., II, via versatile straightforward synthetic routes. All the synthesized compounds have been characterized by IR, ¹H NMR, ¹³C NMR, mass spectroscopy, and elemental analyses and then have been examined for their in vitro antiviral activity against HPV, genotype 18. Two compounds, I and II, were the most promising HR-HPV inhibitors with a percentage of 95.00 and 96.84%, resp. Both compounds demonstrated a substantial down-regulation of HPV oncoproteins E6 and E7 with up-regulation of tumor suppressor proteins, p53, and pRb, resp. using western blot technique. Furthermore, the cytotoxicity of compounds I and II against the cervical cancer Hela cell line was further examined Compound I exhibited strong anticancer activity with IC₅₀ 0.08μM, which is equivalent to 5-FU (IC₅₀ 0.09μM). The cell cycle anal. was performed for investigating the potential mechanism of compound I, resulting in a significant accumulation of the cell population in both pre-G1 and G0-G1 phases and arrest the cell cycle at G1 phase. Addnl., compound I induced apoptosis, triggering cell death via increasing the early and late apoptotic rates by approx. 16 and 188 folds compared with the control. The most cytotoxic agent, I, revealed a remarkable inhibition of the targeted carbonic anhydrase IX enzyme with an IC₅₀ value of 0.12μM comparable to the standard drug. In addition, the ADME profiles of the most highly successful derivatives have been studied in order to determine their ability to be produced as good drug candidates.

Zhang, Shui-Juan published the artcileIntracerebroventricular injection of leukotriene B₄ attenuates antigen-induced asthmatic response via BLT1 receptor stimulating HPA-axis in sensitized rats, Synthetic Route of 321673-30-7, the publication is Respiratory Research (2010), No pp. given, database is CAplus and MEDLINE.

Basic and clin. studies suggest that hypothalamic-pituitary-adrenal (HPA) axis is the neuroendocrine-immune pathway that functionally regulates the chronic inflammatory disease including asthma. Our previous studies showed corresponding changes of cytokines and leukotriene B₄ (LTB₄) between brain and lung tissues in antigen-challenged asthmatic rats. Here, we investigated how the increased LTB₄ level in brain interacts with HPA axis in regulating antigen-induced asthmatic response in sensitized rats. Ovalbumin-sensitized rats were challenged by inhalation of antigen. Rats received vehicle, LTB₄ or U75302 (a selective LTB₄ BLT1 receptor inhibitor) was given via intracerebroventricular injection (i.c.v) 30 min before challenge. Lung resistance (R_L) and dynamic lung compliance (C_dyn) were measured before and after antigen challenge. Inflammatory response in lung tissue was assessed 24 h after challenge. Expression of CRH mRNA and protein in hypothalamus were evaluated by RT-PCR and Western Blot, and plasma levels of adrenocorticotropic hormone (ACTH) and corticosterone (CORT) were measured using the ELISA kits. Antigen challenge decreased pulmonary function and induced airway inflammation, evoked HPA axis response in sensitized rats. Administration of LTB₄ via i.c.v markedly attenuated airway contraction and inflammation. Meanwhile, LTB₄ via i.c.v markedly increased CORT and ACTH level in plasma before antigen challenge, and followed by further increases in CORT and ACTH levels in plasma after antigen challenge in sensitized rats. Expression of CRH mRNA and protein in hypothalamus were also significantly increased by LTB₄ via i.c.v in sensitized rats after antigen challenge. These effect were completely blocked by pre-treatment with BLT1 receptor antagonist U75302 (10 ng), but not by BLT2 antagonist LY255283. LTB₄ administered via i.c.v down-regulates the airway contraction response and inflammation through activation of the HPA axis via its BLT1 receptor. This study expands our concept of the regulatory role of intracranial inflammatory mediators in inflammatory diseases including asthma. The favorable effects of LTB₄ on the HPA axis may help to explain the phenomenon of self-relief after an asthmatic attack.
