tuberculosis. This review also aims to highlight a large gap in our knowledge of pathogen physiology the interplay between metal homeostasis and central carbon metabolism, two cellular processes which are usually studied separately. Integrating metabolism and metal biology would allow the discovery of new weaknesses in bacterial physiology, leading to the development of novel and improved antibacterial therapies.As a source of therapeutic agents, heterocyclic nitrogen-containing compounds and their derivatives are still interesting and essential. Pyrazole, a five-member heteroaromatic ring with two nitrogen atoms, has a major impact on chemical industries as well as pharmaceutical industries. Due to its wide range of biological activities against various diseases, it has been identified as a biologically important heterocyclic scaffold. The treatment of neurological disorders has always been a difficult task. Therefore, identifying therapeutically effective molecules for neurological conditions remains an open challenge in biomedical research and development. For developing novel entities as neuroprotective agents, recently, pyrazole scaffold has attracted medicinal chemists worldwide. The major focus of research in this area is to discover novel molecules as neuroprotective agents with minimal adverse effects and better effectiveness in improving the neurological condition. This review mainly covers recent developments in the neuropharmacological role of pyrazole incorporated compounds, including their structural-activity relationship (SAR), which also further includes IC50 values (in mM as well as in μM), recent patents, and a brief history as neuroprotective agents.

Prostate cancer (PCa) is the fourth most common tumor in males.

To investigate effects of atorvastatin (AS) on PCa cells proliferation and clarify the associated mechanisms.

PCa cell lines were cultured and treated with irradiation (IR) (4 Gy), AS (6 μg/ml), transfected with Bcl-2 siRNA, and then divided into different groups. Xenograft tumor mouse model was established. Bcl-2 and MSH2 gene transcription and protein expression were evaluated using RT-PCR assay and western blot assay. Plate clone formation assay was employed to examine colony formation. MTT assay was used to detect cell viabilities. Flow cytometry analysis was utilized to verify apoptosis. Co-immunoprecipitation and immuno-fluorescence assay were used to identify interaction between Bcl-2 and MSH2.

IR significantly reduced colony formation, enhanced Bcl-2 and reduced MSH2 gene transcription in PCa cells compared to un-treated cells (p<0.05). AS significantly strengthened radio-therapeutic effects of IR on colony formation, decreased cell apoptosis and increased Bcl-2 gene transcription/protein expression in PCa cells compared to single IR treatment cells (p<0.05). AS combining IR down-regulated MSH2 gene transcription/protein expression in PCa cells compared to single IR treatment cells (p<0.05). Bcl-2 interacted with MSH2 both in PCa cells and tumor tissues administrating with AS. AS enhanced reductive effects of IR on tumor size of Xenograft tumor mice.

Atorvastatin administration enhanced inhibitory effects of IR either on PCa cells or on tumor size of Xenograft tumor mice. The inhibitory effects of atorvastatin were mediated by reducing MSH2 expression and triggering interaction between Bcl-2 and MSH2, both in vitro and in vivo levels.

The clinical outcomes of patients with acute myeloid leukemia (AML) remain unsatisfactory, therefore the development of more efficacious and better-tolerated therapy for AML is critical. We have previously reported the anti-leukemic activity of synthetic halohydroxyl dimeric naphthoquinones (BiQ) and aziridinyl BiQ.

This study aimed to improve the potency and bioavailability of BiQ compounds and investigate the anti-leukemic activity of the lead compound in vitro and in a human AML xenograft mouse model.

We designed, synthesized, and performed structure-activity relationship of several rationally designed BiQ analogues that possess amino alcohol functional groups on the naphthoquinone core rings. The compounds were screened for anti-leukemic activity and the mechanism as well as in vivo tolerability and efficacy of our lead compound was investigated.

We report that a dimeric naphthoquinone (designated BaltBiQ) demonstrated potent nanomolar anti-leukemic activity in AML cell lines. BaltBiQ treatment resulted in the generation of reactive oxygen species, induction of DNA damage, and inhibition of indoleamine dioxygenase 1. Although BaltBiQ was tolerated well in vivo, it did not significantly improve survival as a single agent, but in combination with the specific Bcl-2 inhibitor, Venetoclax, tumor growth was significantly inhibited compared to untreated mice.

We synthesized a novel amino alcohol dimeric naphthoquinone, investigated its main mechanisms of action, reported its in vitro anti-AML cytotoxic activity, and showed its in vivo promising activity combined with a clinically available Bcl-2 inhibitor in a patient-derived xenograft model of AML.

The discovery of therapeutic anticancer agents based on natural products is one of the current research focuses. Network pharmacology will broaden our understanding of drug actions by bioinformatics analysis.

To explore the potential and provide scientific evidence for methylaervine as a lead compound against cervical carcinoma.

Methylaervine was synthesized, and its activity against four cancer cell lines was evaluated by MTT assay. Pharmacokinetics properties were obtained by silico approaches, and the pharmacologic mechanism was predicted by network pharmacology. Then we validated and investigated our predictions of candidate targets using a molecular docking study.

Methylaervine was synthesized with a total yield of 54.9%, which displayed activity against HeLa (IC

= 15.4 µM) with good predicted pharmacokinetic properties, thus being considered a potential lead compound. The network pharmacology study indicated that methylaervine could act against cervical carcinoma by regulating the function of multiple pivotal targets, such as CTNNB1, PTPRJ, RPA1, and TJP1, mainly covering cell growth, cell motility, and cell proliferation.
