Chloroquine (CQ) then becomes protonated (to CQ 2+), as the digestive vacuole is known to be acidic (pH 4.7); chloroquine then cannot leave by diffusion. Chloroquine caps hemozoin molecules to prevent further biocrystallization of heme, thus leading to heme buildup. Chloroquine binds to heme (or FP) to form the FP-chloroquine complex; this ...
Fine-needle aspiration (FNA) is a diagnostic procedure used to investigate lumps or masses. In this technique, a thin (23–25 gauge (0.52 to 0.64 mm outer diameter)), hollow needle is inserted into the mass for sampling of cells that, after being stained , are examined under a microscope ( biopsy ).
It is now suggested that it is used in combination with other antimalarial drugs to extend its effective usage. Popular drugs based on chloroquine phosphate (also called nivaquine) are Chloroquine FNA, Resochin and Dawaquin. Chloroquine is a 4-aminoquinolone compound with a complicated

It is approved in the United States as a treatment and preventive measure against malaria. [6] The combination is considered to be more effective in treating malaria caused by Plasmodium falciparum than that caused by P. vivax, for which chloroquine is considered more effective, though in the absence of a species-specific diagnosis, the sulfadoxine-pyrimethamine combination may be indicated.

President Trump has touted the benefits of two drugs studied to treat COVID-19. World-renowned malaria expert Christopher Plowe, PhD, says there's not enough evidence to start prescribing it.
Examples include amodiaquine, chloroquine, and hydroxychloroquine. [3] Other uses for the derivatives are: anti-asthmatic, antibacterial, anti-fungal, anti-malarial, antiviral and anti-inflammatory agents. [1] A patent application for 4-aminoquinoline compounds was filed in 2002 and published in 2005. [4]
