Scientists continue to perform variants on the Miller-Urey experiment to this day, using different chemical baths to reflect current (and differing) theories about the conditions on Earth at the relevant time.
Some have shown less promising results, some have shown more promising results. If any experiments, whether in-lab or computer-modeled, have substantially discredited the 1953 findings, there’s nothing in Wikipedia (take the source for what you will) about it.
