The article was 《Synthesis and biological evaluation of pyrazole linked benzothiazole-β-naphthol derivatives as topoisomerase I inhibitors with DNA binding ability》. The article mentions the following:

A series of new pyrazole linked benzothiazole-β-naphthol derivatives were designed and synthesized using a simple, efficient and ecofriendly route under catalyst-free conditions in good to excellent yields. These derivatives were evaluated for their cytotoxicity on selected human cancer cell lines. Among those, the derivatives 4j, 4k and 4l exhibited considerable cytotoxicity with IC50 values ranging between 4.63 and 5.54 μM against human cervical cancer cells (HeLa). Structure activity relationship was elucidated by varying different substituents on benzothiazoles and pyrazoles. Further, flow cytometric anal. revealed that these derivatives induced cell cycle arrest in G2/M phase and spectroscopic studies such as UV-visible, fluorescence and CD studies showed that these derivatives exhibited good DNA binding affinity. Addnl., these derivatives can effectively inhibit the topoisomerase I activity. Viscosity studies and mol. docking studies demonstrated that the derivatives bind with the minor groove of the DNA.

In 2013,Suzuki, Kenji; Hamada, Yoshio; Nguyen, Jeffrey-Tri; Kiso, Yoshiaki published 《Novel BACE1 inhibitors with a non-acidic heterocycle at the P1′ position》.Bioorganic & Medicinal Chemistry published the findings.Name: 5-Bromothiazol-2-amine The information in the text is summarized as follows:

We have reported potent peptidic and non-peptidic BACE1 inhibitors with a hydroxymethylcarbonyl (HMC) isostere as a substrate transition-state mimic. However, our potent inhibitors possess a tetrazole ring at the P1′ position. It is desirable that central nervous system (CNS) drugs do not possess an acidic moiety. In this study, we synthesized non-acidic BACE1 inhibitors with heterocyclic derivatives at the P1′ position. KMI-1764 I exhibited potent inhibitory activity (IC50 = 27 nM). Interestingly, these non-acidic inhibitors tended to follow the quant. structure-activity relationship (QSAR) equation and interacted with BACE1-Arg235 in the binding model.

Acylaminobenzothiazole hits were identified as potential inhibitors of T. cruzi replication, a parasite responsible for Chagas Disease. We selected compound 1, N-(6-chlorobenzo[d]thiazol-2-yl)cyclopropanecarboxamide, for lead optimization, aiming to improve in parallel its anti-T. cruzi activity (IC50 = 0.630μM) and its human metabolic stability (human clearance = 9.57mL/min/g). A total of 39 analogs of 1 were synthesized and tested in vitro. We established a multiparametric structure activity relationship, allowing optimization of both anti-parasite activity, physicochem. parameters and ADME properties.

The article was titled 《Virtual screening identification and chemical optimization of substituted 2-arylbenzimidazoles as new non-zinc-binding MMP-2 inhibitors》, and you may find the article in Bioorganic & Medicinal Chemistry.Safety of 6-Chlorobenzothiazol-2-ylamine The information in the text is summarized as follows:

Matrix metalloproteinases (MMPs) are a large family of zinc-dependent endoproteases known to exert multiple regulatory roles in tumor progression and invasiveness. This encouraged over the years the approach of MMP, and particularly MMP-2, targeting for anticancer treatment. Early generations of MMP inhibitors, based on aspecific zinc binding groups (ZBGs) assembled on (pseudo)peptide scaffolds, have been discontinued due to the clin. emergence of toxicity and further drawbacks, giving the way to inhibitors with alternative zinc-chelator moieties or not binding the catalytic zinc ion. In the present paper, we continue the search for new non-zinc binding MMP-2 inhibitors: exploiting previously identified compounds, a virtual screening (VS) campaign was carried out and led to the identification of a new class of ligands. The structure-activity relationship (SAR) of the benzimidazole scaffold was explored by synthesis of several analogs whose inhibition activity was tested with enzyme inhibition assays. By performing the mol. simplification approach, we disclosed different sets of single-digit micromolar inhibitors of MMP-2, with up to a ten-fold increase in inhibitory activity and ameliorated selectivity towards off-target MMP-8, compared to selected lead compound Mol. dynamics calculations conducted on complexes of MMP-2 with docked privileged structures confirmed that analyzed inhibitors avoid targeting the zinc ion and dip inside the S1′ pocket. Present results provide a further enrichment of our insights for the design of novel MMP-2 selective inhibitors.

The article was 《Aire-expressing ILC3-like cells in the lymph node display potent APC features》. The article mentions the following:

The autoimmune regulator (Aire) serves an essential function for T cell tolerance by promoting the “”promiscuous”” expression of tissue antigens in thymic epithelial cells. Aire is also detected in rare cells in peripheral lymphoid organs, but the identity of these cells is poorly understood. Here, we report that Aire protein-expressing cells in lymph nodes exhibit typical group 3 innate lymphoid cell (ILC3) characteristics such as lymphoid morphol., absence of “”classical”” hematopoietic lineage markers, and dependence on RORγt. Aire+ cells are more frequent among lineage-neg. RORγt+ cells of peripheral lymph nodes as compared with mucosa-draining lymph nodes, display a unique Aire-dependent transcriptional signature, express high surface levels of MHCII and costimulatory mols., and efficiently present an endogenously expressed model antigen to CD4+ T cells. These findings define a novel type of ILC3-like cells with potent APC features, suggesting that these cells serve a function in the control of T cell responses.
