Severe cutaneous adverse reactions associated with antifungal agents: a pharmacovigilance analysis based on the FDA Adverse Event Reporting System (FAERS) database.

Background: The aim of this study was to explore the risk of severe cutaneous adverse reactions (SCARs) caused by different antifungal drugs in the real world.

Methods: We extracted the data from the FDA Adverse Event Reporting System (FAERS) from January 2004 to December 2022 and performed disproportionality analyses to characterize the signal differences of antifungal agents-related SCARs.

Results: A total of 952 antifungals-related SCARs were identified.

A pharmacovigilance study of chronic kidney disease in diabetes mellitus patients with statin treatment by using the US Food and Drug Administration adverse event reporting system.

Background: Statins were regarded as a main medication for managing hypercholesterolemia. Administration of statin therapy could reduce the incidence of cardiovascular disease in individuals diagnosed with type 2 diabetes mellitus (DM), which was recognized by multipal clinical guidelines. But previous studies had conflicting results on whether the long-term use of statins could benefit the renal function in diabetic patients.

Severe cutaneous adverse reactions due to antibiotics therapy: a pharmacovigilance analysis of FDA adverse event reporting system events.

Background: The aim of this study was to monitor, identify and evaluate severe cutaneous adverse reactions (SCAR) induced by antibiotics in patients.

Methods: Disproportionality algorithms were performed in data mining to screen suspected SCAR after using nine categories of antibiotics based on the FDA's Adverse Event Reporting System (FAERS) from January 2004 to December 2022. The drug information and demographic characteristics of antibiotic-associated SCAR were also investigated.

Case Report: Severe Diarrhea Caused by Diagnosed by Metagenome Next-Generation Sequencing in Blood.

Background: is one of the major pathogens causing diarrhea worldwide. At present, cryptosporidiosis is difficult to prevent and control, especially in immunocompromised hosts. It may cause life-threatening diarrhea and malabsorption among children and immunocompromised patients.

Discovery of 2-Methyl-2-(4-(2-methyl-8-(1-pyrrolo[2,3-]pyridin-6-yl)-1-naphtho[1,2-]imidazol-1-yl)phenyl)propanenitrile as a Novel PI3K/mTOR Inhibitor with Enhanced Antitumor Efficacy and .

PI3K/Akt/mTOR signaling pathway is a validated drug target for cancer treatment that plays a critical role in controlling tumor growth, proliferation, and apoptosis. However, no FDA-approved PI3K/mTOR dual inhibitor exists. Thus, a candidate with a better curative effect and lower toxicity is still urgently needed.

Lead optimization to improve the antiviral potency of 2-aminobenzamide derivatives targeting HIV-1 Vif-A3G axis.

The viral infectivity factor (Vif)-apolipoprotein B mRNA-editing enzyme, catalytic polypeptide-like 3G (APOBEC3G) axis has been recognized as a valid target for developing novel small-molecule therapies for acquired immune deficiency syndrome (AIDS) or for enhancing innate immunity against viruses. Our previous work reported the novel Vif antagonist 2-amino-N-(2-methoxyphenyl)-6-((4-nitrophenyl)sulfonyl)benzamide (2) with strong antiviral activity. In this work, through optimizations of ring C of 2, we discovered the more potent compound 6m with an EC of 0.

Discovery of a novel covalent CDK4/6 inhibitor based on palbociclib scaffold.

Cyclin-dependent kinases 4 and 6 (CDK4/6), which are involved in dynamic regulation of cell cycle, play an indispensable role in controlling the tumor growth. Here, based on the scaffold of palbociclib, we designed and synthesized a series of covalent CDK4/6 inhibitors that targeted amino acid Thr107. The optimized compound C-13 exhibited potent in vitro anticancer activity against CDK4/6 with high selectivity over CDK4/6.

Targeting Cysteine Located Outside the Active Site: An Effective Strategy for Covalent ALKi Design.

Potent inhibitors of ALK are highly desired because of the occurrence of drug resistance. We herein firstly report the development of a rationally designed inhibitor, , which can covalently bind to Cys1259, a cysteine located outside the ALK active site by linking a warhead with Ceritinib through a 2,2'-Oxybis(ethylamine) linker. The and assays showed is a potent selective ALKi with low toxicity to normal cells.

Discovery of a PROTAC targeting ALK with in vivo activity.

Anaplastic lymphoma kinase (ALK) was involved in the development of various cancer types. Although several ALK inhibitors have been advanced to clinical trials, the emergence of drug resistance has limited the clinical application of them. To overcome the drug resistance, proteolysis targeting chimeras (PROTACs) could be an alternative strategy.

Discovery of 4-(3,5-dimethoxy-4-(((4-methoxyphenethyl)amino)methyl)phenoxy)-N-phenylaniline as a novel c-myc inhibitor against colorectal cancer in vitro and in vivo.

Proto-oncogene c-Myc plays an essential role in the development of colorectal cancer (CRC), since downregulation of c-Myc inhibits intestinal polyposis, which is the most cardinal pathological change in the development of CRC. Herein, a series of novel phenoxy-N-phenylaniline derivatives were designed and synthesized. The cytotoxicity activities of all the derivatives were measured by MTT assay in different colon cancer cells, 4-(3,5-dimethoxy-4-(((4-methoxyphenethyl)amino)methyl)phenoxy)-N-phenylaniline (42) was discovered, the lead compound 42 with excellent cytotoxicity activity of IC = 0.

Discovery of 4-phenyl-2H-benzo[b][1,4]oxazin-3(4H)-one derivatives as potent and orally active PI3K/mTOR dual inhibitors.

PI3K/Akt/mTOR signaling pathway plays an important role in cancer cell growth and survival. In this study, a new class of molecules with skeleton of 4-phenyl-2H-benzo[b] [1,4]oxazin-3(4H)-one were designed and synthesized targeting this pathway. Bioassays showed that, among all the molecules, 8d-1 was a pan-class I PI3K/mTOR inhibitor with an IC of 0.
