Abstract
The use of histone deacetylase inhibitors (HDACis) is an effective approach for cancer treatment. In this work, a series of hydroxamic acid-based HDACis with a tetrahydro-β-carboline core and aliphatic linker have been designed and synthesized. The optimal compound 13d potently inhibited HDAC1 and showed good antiproliferative activity against different tumor cell lines in vitro. Molecular docking of 13d was conducted to rationalize the high binding affinity for HDAC1. Therefore, this work provides a new structure design for HDAC inhibitors and also offers a promising treatment for solid tumors.

Abstract
A series of tetrahydro-β-carboline (THβC)-based hydroxamic acids were rationally designed and synthesized as novel selective HDAC6 inhibitors (sHDAC6is) by the application of scaffold hopping strategy. Several THβC analogues were highly potent (IC50 < 5 nM) and selective against HDAC6 enzyme and exhibited good antiproliferative activity against human multiple myeloma (MM) cell. Molecular docking interpreted the structure activity relationship (SAR). Target engagement of HDAC6 was confirmed in RPMI-8226 cells using the WB assay. In vitro, (1S, 3R)-1-(4-chlorophenyl)-N-(4-(hydroxycarbamoyl)benzyl)-2,3,4,9-tetrahydro-1H-pyrido[3, 4-b]indole-3-carboxamide (14g) showed potent broad antiproliferative activity against various tumors including leukemia, colon cancer, melanoma, and breast cancer cell lines, better than ACY-1215. Moreover, 14g also showed good pharmacokinetics properties in mice via oral administration.

Abstract
Herein, a series of novel indole-piperazine derivatives were synthesized. Bioassay results showed the title compounds exhibited moderate to good bacteriostatic efficacy against the test Gram-positive bacteria and Gram-negative bacteria, including methicillin-resistant Staphylococcus aureus (MRSA). Among theses compounds, three remarkable compounds 8f, 9a, and 9h exhibited superior in vitro antibacterial profiles for anti- S. aureus and anti-MRSA to that of gentamicin. Hit compound 9a manifested a rapid bactericidal kinetic effect on MRSA,with no resistance observed after 19 days of sequential passaging. And 8 µg/mL of compound 9a displayed considerable post antibacterial effects to that of ciprofloxacin at the concentration of 2 µg/mL. Cytotoxic and ADMET studies indicated, to some extent, compounds 8f, 9a, and 9h were up to the standard for antibacterial drugs. These results suggest that indole/piperazine derivatives based on the title compounds can serve as a new scaffold for antimicrobial development.

Abstract
Novel indole-piperazine derivatives with a hydroxamic acid moiety were designed and synthesized as selective histone deacetylase 6 (HDAC6) inhibitors. In enzymatic assays, all compounds exhibited nanomolar IC50 values. N-hydroxy-4-((4-(7-methyl-1H-indole-3-carbonyl)piperazin-1-yl)methyl)benzamide, 9c, was the most potent HDAC6 inhibitor (IC50, 13.6 nM). In vitro, 9c induced neurite outgrowth of PC12 cells without producing toxic effects, better than Tubastatin A (Tub A). Additionally, 9c demonstrated blatant neuroprotective activity in PC12 cells against H2O2-induced oxidative damage. In western blot assay, 9c could increase the acetylation of α-tubulin in a dose-dependent manner.

Abstract
2,5-Diketopiperazine derivatives, consisting of benzylidene and alkylidene substituents at 3 and 6 positions, have been considered as a core structure for their antiviral activities. Herein, the novel N-substituted 2,5-Diketopiperazine derivatives were successfully prepared and their antiviral activities against influenza virus were evaluated by monitoring viral propagation in embryonated chicken eggs. It was found that (3Z,6Z)-3-benzylidene-6-(2-methyl propylidene)-4-substituted-2,5-Diketopiperazines (13b–d), (3Z,6E)-3-benzylidene-6-(2-methylpropyli dene)-1-(1-ethyl pyrrolidine)-2,5-Diketopiperazine (14c), and Lansai-C exhibited negative results in influenza virus propagation at a concentration of 25 µg/mL. Additionally, molecular docking study revealed that 13b–d and 14c bound in 430-cavity of neuraminidase from H5N2 avian influenza virus and the synthesized derivatives also strongly interacted with the key amino acid residues, including Arg371, Pro326, Ile427, and Thr439.
