ETx-22, a Novel Nectin-4-Directed Antibody-Drug Conjugate, Demonstrates Safety and Potent Antitumor Activity in Low-Nectin-4-Expressing Tumors.

ETx-22, a novel ADC combining a tumor nectin-4-specific antibody and an innovative linker to exatecan, demonstrates significant and durable responses in low-target-expressing tumor models that are resistant to MMAE-based EV and has a better toxicity profile. This new ADC has the potential to benefit additional patient populations beyond its current indication.

Information management for entomology screening.

The successful introduction of genetically modified (GM) crops has created a revolutionary transformation of the agricultural industry with GM crops currently planted on some 130 million acres. Historically, agricultural companies were involved in the discovery of conventional insecticide chemistries in processes that were very similar to those in the pharmaceutical industry. With the introduction of GM technologies, the process has radically changed.

The selectivity of MDL 74,721 in models of neurogenic versus vascular components of migraine.

MDL 74,721 (R)-2-(N1,N1-dipropylamino)-8-methylaminosulfonylmethyl-1,2,3,4-te trahydronaphthalene, a sulfonamidotetralin, has been found to exhibit a 10,000-fold greater potency in neurogenic versus vascular models of migraine. Sumatriptan, a relatively pure 5-HT1D/5-HT1B receptor agonist, also showed higher potency versus neurogenic inflammation. However, for sumatriptan the potency difference (100-fold) in the two pathophysiological models was less pronounced than seen for MDL 74,721.
