Which hormone(s) is/are required for facultative water reabsorption in the collecting ducts?
ADH hormones are required for facultative water reabsorption in the collecting ducts.
What about facultative water reabsorption?The antidiuretic hormone is the hormone in charge of facultative water reabsorption (ADH). By enhancing the water permeability of key cells in the collecting duct and the last segment of the distal convoluted tubule, facultative water reabsorption is achieved. The proximal convoluted tubule is the initial area of the nephron that is in charge of reabsorbing water. The proximal tubule receives filtered fluid from Bowman's capsule. Antidiuretic hormone increases the reabsorption of water into the circulation by binding to receptors on cells in the kidney's collecting ducts. The collecting ducts are essentially impermeable to water in the absence of antidiuretic hormone, and water escapes as urine.In facultative reabsorption, water is reabsorbed through osmosis because the impact of ADH makes the collecting ducts more permeable to water.Learn more about hormone here:

Disruption of axonal transport would be a good target for his drug.
What is disruption of axonal transport?Axonal transport defects are among the early molecular events leading to neurodegeneration in mouse models of amyotrophic lateral sclerosis (ALS).Gene expression profiles indicate that dynactin-1 mRNA is downregulated in degenerating spinal motor neurons of autopsied patients with sporadic ALS. Disruption of axonal transport also underlies the pathogenesis of spinal muscular atrophy and hereditary spastic paraplegias.The neurotoxin β,β′-iminodipropionitrile (IDPN) selectively disrupts slow axonal transport without affecting fast anterograde or retrograde axonal transport.Impairment of slow axonal transport causes a proximal accumulation of neurofilaments. Because neurofilaments regulate axonal diameter, this accumulation leads to a marked swelling of the axon.Acrylamide causes decreased axonal transport, also causing proximal accumulations of neurofilaments and swelling.To learn more about axonal transport,

In a muscle contraction, the force that shortens the sarcomeres comes from the myosin cross-bridges pulling on the actin filaments.
A myosin head essentially functions like a cocked spring that bends and delivers a power stroke when it binds to an actin filament. A single sarcomere is forced to contract and shortens as a result of the power stroke's actin filament sliding past the myosin.
If there is enough ATP and the myosin-binding sites are exposed, myosin binds to actin to start the cross-bridge cycling process. The muscle contracts as the sarcomere shortens. Since this binding cannot take place without calcium, free calcium is a crucial regulator of muscle contraction.
