Abstract
Schistosomiasis is a prevalent yet neglected tropical parasitic disease caused by the Schistosoma genus of blood flukes. Praziquantel is the only currently available treatment, hence drug resistance poses a major threat. Recently, histone deacetylase 8 (HDAC8) selective inhibitors have been proposed as a viable treatment for schistosomiasis. Herein, we report the phenotypic screening of a focused library of small molecules of varying HDAC isozyme-inhibition profiles, including eight HDAC8 inhibitors with >10-fold selectivity in comparable functional inhibition assays and IC50 values against HDAC8<100 nM. HDAC8-selective inhibitors showed the lowest potency against Schistosoma mansoni newly transformed schistosomula (NTS). Pan-HDAC inhibitors MMH258, MMH259, and MMH373, as assessed by functional inhibition assays, with minimal or no-observed hHDAC8 and SmHDAC8 activities, were active against both NTS (MMH258, IC50 =1.5 μM; MMH259, IC50 =2.3 μM) and adult S. mansoni (MMH258, IC50 =2.1 μM; MMH373, IC50 =3.4 μM). Our results indicate that neither hHDAC8 nor SmHDAC8 activity were directly correlated to their NTS and adult S. mansoni activities.

Abstract
![]()
Sirtuin 6 (SIRT6)
is an NAD+-dependent protein deacylase
and mono-ADP-ribosyltransferase of the sirtuin family with a wide
substrate specificity. In vitro and in vivo studies have indicated that SIRT6 overexpression or activation has
beneficial effects for cellular processes such as DNA repair, metabolic
regulation, and aging. On the other hand, SIRT6 has contrasting roles
in cancer, acting either as a tumor suppressor or promoter in a context-specific
manner. Given its central role in cellular homeostasis, SIRT6 has
emerged as a promising target for the development of small-molecule
activators and inhibitors possessing a therapeutic potential in diseases
ranging from cancer to age-related disorders. Moreover, specific modulators
allow the molecular details of SIRT6 activity to be scrutinized and
further validate the enzyme as a pharmacological target. In this Perspective,
we summarize the current knowledge about SIRT6 pharmacology and medicinal
chemistry and describe the features of the activators and inhibitors
identified so far.

Abstract
It is now 30 years since the first report of a potent zinc-dependent histone deacetylase (HDAC) inhibitor appeared. Since then, five HDAC inhibitors have received regulatory approval for cancer chemotherapy while many others are in clinical development for oncology as well as other therapeutic indications. This Perspective reviews the biological and medicinal chemistry advances over the past 3 decades with an emphasis on the design of selective inhibitors that discriminate between the 11 human HDAC isoforms.
