Oncolytic viruses (OVs) are emerging as a promising therapeutic approach for treating cancer. OVs are capable of both tumor-specific cell lysis and immune stimulation and can be optimized for enhanced tumor selectivity.  WuXi AppTec offers a comprehensive platform of OV-related services, including virus engineering and validation, immune profiling and lysis assays, tumor cell selectivity assays, …Read More >

WuXi AppTec scientists contributed to a study which identified a novel, indole-based, selective estrogen receptor degrader (SERD), designated LX-039. The authors show that LX-039 exhibits potent activity in ER degradation and proliferation assays. With favorable ADME/PK properties, LX-039 also exhibits higher efficacy in a tamoxifen-resistant MCF7 CDX model compared to fulvestrant, with up to 90% inhibition …Read More >

WuXi AppTec scientists collaborated on a study to characterize a series of pyrroloquinoline derivatives that were designed and synthesized to understand the effect of various substitutions on human cytomegalovirus (HCMV) polymerase activity, antiviral activity, and hERG inhibition.  Results suggest that substitutions can be fine-tuned to reduce hERG inhibition while maintaining HCMV antiviral potency. The abstract …Read More >

Learn how parallel medicinal chemistry (PMC) and high throughput experimentation (HTE) combined with machine learning can provide a more focused approach to target molecules, resulting in a more concentrated set of compounds to make the process of lead selection easier. Our experts show how PMC can shorten the turnaround time of the design-synthesis-test cycle, providing …Read More >
