Among them, compound I [R¹ = 2-furylmethyl; R² = 2-MeO; R³ = (2-aminopyrimidin-4-yl)oxy] exhibited potent inhibitory effect on HBV DNA replication in both wild type and drug resistant (lamivudine and entecavir) HBV strains with IC₅₀ values of 0.15 and 0.10μM, resp. Notably, the selective index value of I [R¹ = 2-furylmethyl; R² = 2-MeO; R³ = (2-aminopyrimidin-4-yl)oxy] was high above 66.67, indicating the favorable safety profile. Mol. docking study indicated that compound I [R¹ = 2-furylmethyl; R² = 2-MeO; R³ = (2-aminopyrimidin-4-yl)oxy] well fitted into the binding pocket of TLR8 protein-protein interface. Dual-luciferase reporter gene assay further confirmed that compound I [R¹ = 2-furylmethyl; R² = 2-MeO; R³ = (2-aminopyrimidin-4-yl)oxy] could dose-dependently activate TLR8, thus effectively inducing the activity of TLR8-dependent NF-κB. Collectively, compound I [R¹ = 2-furylmethyl; R² = 2-MeO; R³ = (2-aminopyrimidin-4-yl)oxy] displayed potent anti-HBV activities and TLR8 agonist effect in vitro, and might be a potential immunomodulatory anti-HBV agent to warrant further investigation.

Qiu, Jingying;Zou, Yueting;Liu, Qingchuan;Jiang, Chunyu;Zhou, Qingqing;Li, Shuqiong;Chen, Wang;Li, Zheng;Gu, Xiaoke research published 《 Synthesis and Evaluation of Novel Quinazolinone Derivatives as Potential Anti-HCC Agents》, the research content is summarized as follows. Hepatocellular carcinoma (HCC), a common malignancy worldwide, has a high mortality rate and limited effective therapeutic options. In this work, a series of quinazolinone compounds (6a-t and 7a-i) were synthesized as potential anti-HCC agents. Among them, compound 7b more potently inhibited HepG2, HUH7 and SK-Hep-1 cells proliferation than classical anti-HCC drug sorafenib, indicating its potential anti-HCC effect. Interestingly, 7b could dose-dependently decrease Cyclin D1 and CDK2 levels, and increase p21 protein expression, thus inducing HepG2 cells cycle arrest at G0/G1 phase. In addition, 7b also displayed potent apoptosis-induced effect on HepG2 cells by interfering Hepatocellular carcinoma, Bcl-2 and Bcl-xl proteins expression. Notably, 7b could efficiently block the activity of PI3K pathway by dose-dependently reducing the phosphorylation of PI3K (Y607) and AKT (S473). Moreover, predicted ADME properties indicated that 7b possessed a good pharmacokinetic profile. Collectively, compound 7b might be a promising lead to the development of novel therapeutic agents towards HCC.

Punetha, Ankita;Green, Keith D.;Garzan, Atefeh;Thamban Chandrika, Nishad;Willby, Melisa J.;Pang, Allan H.;Hou, Caixia;Holbrook, Selina Y. L.;Krieger, Kyle;Posey, James E.;Parish, Tanya;Tsodikov, Oleg V.;Garneau-Tsodikova, Sylvie research published 《 Structure-based design of haloperidol analogues as inhibitors of acetyltransferase Eis from Mycobacterium tuberculosis to overcome kanamycin resistance》, the research content is summarized as follows. Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb), is a deadly bacterial disease. Drug-resistant strains of Mtb make eradication of TB a daunting task. Overexpression of the enhanced intracellular survival (Eis) protein by Mtb confers resistance to the second-line antibiotic kanamycin (KAN). Eis is an acetyltransferase that acetylates KAN, inactivating its antimicrobial function. Development of Eis inhibitors as KAN adjuvant therapeutics is an attractive path to forestall and overcome KAN resistance. We discovered that an antipsychotic drug, haloperidol (HPD, 1), was a potent Eis inhibitor with IC₅₀ = 0.39 ± 0.08 μM. We determined the crystal structure of the Eis-haloperidol (1) complex, which guided synthesis of 34 analogs. The structure-activity relationship study showed that in addition to haloperidol (1), eight analogs, some of which were smaller than 1, potently inhibited Eis (IC₅₀ ≤ 1 μM). Crystal structures of Eis in complexes with three potent analogs and droperidol (DPD), an antiemetic and antipsychotic, were determined Three compounds partially restored KAN sensitivity of a KAN-resistant Mtb strain K204 overexpressing Eis. The Eis inhibitors generally did not exhibit cytotoxicity against mammalian cells. All tested compounds were modestly metabolically stable in human liver microsomes, exhibiting 30-60% metabolism over the course of the assay. While direct repurposing of haloperidol as an anti-TB agent is unlikely due to its neurotoxicity, this study reveals potential approaches to modifying this chem. scaffold to minimize toxicity and improve metabolic stability, while preserving potent Eis inhibition.

Herein, the synthesis of the first series of heterobivalent ligands targeting the putative heteromeric 5-HT_2A/mGlu₂ receptor complex, based on the 5-HT_2A antagonist MDL-100,907 and the mGlu₂ ago-PAM JNJ-42491293, are reported. The functional properties of monovalent and heterobivalent ligands were characterized in 5-HT_2A-, mGlu₂/Gqo5-, 5-HT_2A/mGlu₂-, and 5-HT_2A/mGlu₂/Gqo5-expressing HEK293 cells using a Ca²⁺ imaging assay and a [³H]ketanserin binding assay. Pronounced functional crosstalk was observed between the two receptors in 5-HT_2A/mGlu₂ and 5-HT_2A/mGlu₂/Gqo5 cells. While the synthesized monovalent ligands retained the 5-HT_2A antagonist and mGlu₂ ago-PAM functionalities, the seven bivalent ligands inhibited 5-HT-induced responses in 5-HT_2A/mGlu₂ cells and both 5-HT- and Glu-induced responses in 5-HT_2A/mGlu₂/Gqo5 cells. However, no definitive correlation between the functional potency and spacer length of the ligands was observed, an observation substantiated by the binding affinities exhibited by the compounds in 5-HT_2A, 5-HT_2A/mGlu₂, and 5-HT_2A/mGlu₂/Gqo5 cells. In conclusion, while functional crosstalk between 5-HT2A and mGlu2 was demonstrated, it remains unclear how these heterobivalent ligands interact with the putative receptor complex.

A selective Pd-catalyzed C(3)-H cis-functionalization of piperidine and tetrahydropyran carboxylic acids is achieved using a C(4) aminoquinoline amide auxiliary. High mono- and cis-selectivity is attained by using mesityl carboxylic acid as an additive. Conditions are developed with significantly lower reaction temperatures (≤50°C) than other reported heterocycle C(sp³)-H functionalization reactions, which is facilitated by a DoE optimization. A one-pot C-H functionalization-epimerization procedure provides the trans-3,4-disubstituted isomers directly. Divergent aminoquinoline removal is accomplished with the installation of carboxylic acid, alc., amide and nitrile functional groups. Overall, fragment compounds suitable for screening are generated in 3-4 steps from readily-available heterocyclic carboxylic acids.

C. research published 《 Metallaphotoredox aryl and alkyl radiomethylation for PET ligand discovery》, the research content is summarized as follows. Positron emission tomog. (PET) radioligands (radioactively labeled tracer compounds) are extremely useful for in vivo characterization of central nervous system drug candidates, neurodegenerative diseases and numerous oncol. targets¹. Both tritium and carbon-11 radioisotopologues are generally necessary for in vitro and in vivo characterization of radioligands², yet there exist few radiolabelling protocols for the synthesis of either, inhibiting the development of PET radioligands. The synthesis of such radioligands also needs to be very rapid owing to the short half-life of carbon-11. Here we report a versatile and rapid metallaphotoredox-catalyzed method for late-stage installation of both tritium and carbon-11 into the desired compounds via methylation of pharmaceutical precursors bearing aryl and alkyl bromides. Me groups are among the most prevalent structural elements found in bioactive mols., and so this synthetic approach simplifies the discovery of radioligands. To demonstrate the breadth of applicability of this technique, we perform rapid synthesis of 20 tritiated and 10 carbon-11-labeled complex pharmaceuticals and PET radioligands, including a one-step radiosynthesis of the clin. used compounds [¹¹C]UCB-J and [¹¹C]PHNO. We further outline the direct utility of this protocol for preclin. PET imaging and its translation to automated radiosynthesis for routine radiotracer production in human clin. imaging. We also demonstrate this protocol for the installation of other diverse and pharmaceutically useful isotopes, including carbon-14, carbon-13 and deuterium.
