Abstract
Omics-based technologies are driving major advances in precision medicine, but efforts are still required to consolidate their use in drug discovery. In this work, we exemplify the use of multi-omics to support the development of 3-chloropiperidines, a new class of candidate anticancer agents. Combined analyses of transcriptome and chromatin accessibility elucidated the mechanisms underlying sensitivity to test agents. Furthermore, we implemented a new versatile strategy for the integration of RNA- and ATAC-seq (Assay for Transposase-Accessible Chromatin) data, able to accelerate and extend the standalone analyses of distinct omic layers. This platform guided the construction of a perturbation-informed basal signature predicting cancer cell lines' sensitivity and to further direct compound development against specific tumor types. Overall, this approach offers a scalable pipeline to support the early phases of drug discovery, understanding of mechanisms, and potentially inform the positioning of therapeutics in the clinic.

Abstract
Polyketides are a large group of secondary metabolites that have notable variety in their structure and function. Polyketides exhibit a wide range of bioactivities such as antibacterial, antifungal, anticancer, antiviral, immune-suppressing, anti-cholesterol, and anti-inflammatory activity. Naturally, they are found in bacteria, fungi, plants, protists, insects, mollusks, and sponges. Streptomyces is a genus of Gram-positive bacteria that has a filamentous form like fungi. This genus is best known as one of the polyketides producers. Some examples of polyketides produced by Streptomyces are rapamycin, oleandomycin, actinorhodin, daunorubicin, and caprazamycin. Biosynthesis of polyketides involves a group of enzyme activities called polyketide synthases (PKSs). There are three types of PKSs (type I, type II, and type III) in Streptomyces responsible for producing polyketides. This paper focuses on the biosynthesis of polyketides in Streptomyces with three structurally-different types of PKSs.

Abstract
Genotoxic treatments, such as UV light, camptothecin, and adozelesin, stall DNA replication and subsequently generate DNA strand breaks. Typically, DNA breaks are reflected by an increase in ataxia and Rad-related kinase (ATR)-regulated phosphorylation of H2AX (gammaH2AX) and require replication fork movement. This study examined the potential of the monofunctional DNA alkylating agent hedamycin, a powerful inhibitor of DNA replication, to induce DNA strand breaks, phosphorylated H2AX (gammaH2AX) foci, and chromosome aberrations. Hedamycin treatment of HCT116 carcinoma cells resulted in a rapid induction of DNA strand breaks accompanied by increasing H2AX phosphorylation and focalization. Unlike many other treatments that also stall replication, such as UV, camptothecin, and adozelesin, gammaH2AX formation was not suppressed in ATR-compromised cells but actually increased. Similarly, hedamycin induction of gammaH2AX is not dependent on ataxia telangiectasia mutated or DNA-protein kinase, and pretreatment of cells with the phosphatidylinositol 3-kinase-related kinase inhibitor caffeine did not substantially reduce induction of H2AX phosphorylation by hedamycin. Furthermore, the DNA replication inhibitor aphidicolin only modestly depressed hedamycin-induced gammaH2AX formation, indicating that hedamycin-induced DNA double-strand breaks are not dependent on fork progression. In contrast, camptothecin- and adozelesin-induced gammaH2AX was strongly suppressed by aphidicolin. Moreover, after 24 hours following a short-term hedamycin treatment, cells displayed high levels of breaks in interphase nuclear DNA and misjoined chromosomes in metaphase cells. Finally, focalization of a tightly bound form of Ku80 was observed in interphase cells, consistent with the subsequent appearance of chromosomal aberrations via abnormal nonhomologous end joining. Overall, this study has revealed a disparate type of DNA damage response to stalled replication induced by a bulky DNA adduct inducer, hedamycin, that seems not to be highly dependent on ATR or DNA replication.
