- Abstract
- Two approaches were used to design inhibitors of the metalloenzyme carbonic anhydrase (CA, EC
4.2.1.1): the tail and the ring approaches. Aliphatic sulfamates constitute a class ofCAinhibitors (CAIs)
that cannot be classified in either one of these categories. Wereport here the detailed inhibition profile of
four such compounds against isoforms CAs I-XIV, the first crystallographic structures of these
compounds in adduct with isoform II, and molecular modeling studies for their interaction with hCA
IX. Aliphatic monosulfamates/bis-sulfamates were nanomolar inhibitors of hCAs II, IX, and XII,
unlike aromatic/heterocyclic sulfonamides that promiscuously inhibit most CA isozymes with low
nanomolar affinity. The bis-sulfamates incorporating 8 or 10 carbon atoms showed higher affinity for
the tumor-associated hCA IX compared to hCA II, whereas the opposite was true for the monosulfamates.
The explanation for their interaction with CA active site furnishes insights for obtaining
compounds with increased affinity/selectivity for various isozymes.
Introduction
A paradigm in carbonic anhydrase (CA,a EC 4.2.1.1) drug
design was that aliphatic sulfonamidesRSO2NH2 (R=aliphatic
group) are inactive as inhibitors, unlike the aromatic/heterocyclic
ones of the type ArSO2NH2.1 This view was subsequently
challenged, being shown that aliphatic sulfonamides
incorporating perhaloalkyl moieties of the type CnX2nþ1SO2-
NH2 (n=1-4, X=F, Cl),2 as well as various aliphatic
sulfamates/bis-sulfamates3-5 potently inhibit several CA isozymes
involved in fundamental physiologic/pathologic states.
Indeed, this family of metalloenzymes comprises 16 different
isoforms, of which several are cytosolic (CAs I-III, CA VII,
and CAXIII), five are membrane-bound (CA IV, CAIX, CA
XII, CA XIV, and CA XV), two are mitochondrial (CAs VA
and VB), and one (CA VI) is secreted into saliva/milk.6-13
Three acatalytic forms are also known, i.e., CA VIII, CA X,
and CA XI.9 These enzymes are involved in crucial physiological
processes connected with respiration and transport of
CO2/bicarbonate betweenmetabolizing tissues and lungs, pH
and CO2 homeostasis, electrolyte secretion in a variety of
tissues/organs, biosynthetic reactions (such as gluconeogenesis,
lipogenesis, and ureagenesis), bone resorption, calcification,
tumorigenicity, and (literal)
