There are only eight approved small molecule antiviral drugs for treating *** them,four are nucleotide analogues(remdesivir,JT001,molnupiravir,and azvudine),while the other four are protease inhibitors(nirmatrelvir,ensitrelvir,leritrelvir,and simnotrelvir-ritonavir).Antiviral resistance,unfavourable drug‒drug interaction,and toxicity have been reported in previous *** there is a dearth of new treatment options for *** this work,a three-tier cell-based screening was employed to identify novel compounds with anti-SARS-CoV-2 *** compound,designated 172,demonstrated broad-spectrum antiviral activity against multiple human pathogenic coronaviruses and different SARS-CoV-2 variants of *** studies validated by reverse genetics showed that compound 172 inhibits the 3-chymotrypsin-like protease(3CLpro)by binding to an allosteric site and reduces 3CLpro dimerization.A drug synergistic checkerboard assay demonstrated that compound 172 can achieve drug synergy with nirmatrelvir in *** vivo studies confirmed the antiviral activity of compound 172 in both Golden Syrian Hamsters and K18 humanized ACE2 ***,this study identified an alternative druggable site on the SARS-CoV-23CLpro,proposed a potential combination therapy with nirmatrelvir to reduce the risk of antiviral resistance and shed light on the development of allosteric protease inhibitors for treating a range of coronavirus diseases.

Delayed diagnosis of 22q11.2 deletion syndrome in an adult Chinese lady

引用

Chinese Medical Journal 2012年第16期125卷 2945-2947页

作者： SHEA Yat-fung LEE Chi-ho Harinder Gill ChoW wing-sun LAM Yui-ming LUK ho-ming LAM Stephen Tak-sum chu Leung-wing Department of Medicine Queen Mary Hospital the University ofHong Kong Hong Kong China Clinical Genetic Service Department of Health The Government of Hong Kong Special Administrative Region Hong Kong China

We report a 32 year-old Chinese lady with history of tetralogy of Fallot, presented to us with chest pain due to hypocalcemia secondary to hypoparathyroidism. With her dysmerphic facial features and intellectual disability 22q11.2 deletion was suspected and confirmed by genetic study. Clinicians should consider the diagnosis of DiGeorge syndrome in adult patient with past medical history of congenital heart disease, facial dysmorphism, intellectual disability and primary hypoparathyroidism.
