In a single internally consistent radioligand series measuring inhibition of I-NDP-alpha-MSH binding to membranes from BHK570 cells stably expressing each human receptor, bremelanotide returned Ki values of 0.25 nM at MC4R, 6.4 nM at MC1R, 17 nM at MC5R and 53 nM at MC3R, corresponding to pKi 9.6, 8.2, 7.8 and 7.3 respectively
One study warns that these drugs produce unsustainable volumes of toxic waste and non-degradable solid supports ( [20] ), prompting CDMOs to pursue greener chemistries and solvent-recovery systems (for example, water-based or continuous SPPS) as part of future-capex planning ( [21] ) ( [20] )
