ABSTRACT: Herein, we describe the design and applicationof two small-molecule anti-HIV compounds for the creation ofchemically programmed antibodies. N-Acyl-β-lactam deriva-tives of two previously described molecules BMS-378806 andBMS-488043 that inhibit the interaction between HIV-1gp120 and T-cells were synthesized and used to program thebinding activity of aldolase antibody 38C2. Discovery of asuccessful linkage site to BMS-488043 allowed for the synthesis of chemically programmed antibodies with affinity for HIV-1gp120 and potent HIV-1 neutralization activity. Derivation of a successful conjugation strategy for this family of HIV-1 entryinhibitors enables its application in chemically programmed antibodies and vaccines and may facilitate the development of novelbispecific antibodies and topical microbicides.
KEYWORDS: Bioconjugation, anti-HIV agent, chemically programmed antibody, microbicide, entry inhibitor
The retrovirus HIV-1, which causes acquired immunedeficiency syndrome (AIDS), has infected 34 million
people worldwide, and this number is expected to increase by2.5 million each year into the near future.1 Although thecombination reverse transcriptase inhibitor/protease inhibitortreatment known as HAART has proven successful,2,3 sideeffects and viral escape are significant issues, and newtreatments are needed. The viral envelope protein gp120, theprimary target for antibody mediated viral neutralization, is anemerging target for small molecule treatment of HIVinfection.4,5 This protein is responsible for the entry of HIVinto host cells. In the initial step of entry, gp120 binds to theCD4 glycoprotein expressed on the surface of human immunecells. Bristol−Myers Squibb Pharmaceutical Research Institutediscovered small molecules BMS-378806 (1) and BMS-488043(2) that bind to gp120 (Figure 1) and block its interaction with
CD4.6−11 However, the short pharmacokinetic profiles of thesesmall molecule inhibitors (half-lives after intravenous injectionare 0.3 and 2.4 h, respectively) may limit their clinicalapplication.We hypothesize that the pharmacokinetic properties of these
small molecule gp120 inhibitors can be improved byconjugation with a monoclonal antibody (mAb) (Scheme1).12−21 Furthermore, coupling of the small molecule to the
mAb could further enhance their activity in vivo throughantibody effector functions such as antibody dependent cellularcytotoxicity (ADCC) and complement dependent cytotoxicity(CDC). Recently, we have described the development ofchemically programmed antibodies based on the use of mAb38C2, an aldolase antibody generated by reactive immunizationby using a 1,3-diketone hapten.22−24 This antibody possesses alow pKa lysine residue in its binding site that is key to itsaldolase activity that can be site-selectively labeled with N-acyl-β-lactams to produce a chemically programmed antibody.Chemically programmed antibodies have duration times aftersystemic dosing that depend on the properties of the antibodyrather than on those of the conjugated small molecule,providing for very significant extensions in the pharmacokineticprofiles of the attached molecule.18,20 We have demonstratedthe utility of this approach by preparing mAb conjugates thatshow promising activity in a variety of cancer models but also inthe area of anti-infectives through the preparation of CCR5blocking mAbs that inhibit HIV-1 entry and neuraminidaseinhibitors that neutralize influenza.18−20
Treatment as well as prophylaxis of HIV-1 infection requiresthe development of a cocktail of inhibitors. In order tocomplement our anti-CCR5 blockade based on this strategy,18
we envisioned that the conjugate of mAb 38C2 and the small-molecule gp120 inhibitor would bind to gp120 and inhibitCD4-mediated entry of HIV-1 into cells (Scheme 2). In relatedwork, Spiegel and co-workers recently reported that a derivativeof HIV-1 inhibitor 1 modified with a 1,3-dinitrophenyl haptenmoiety binds to HIV gp120.25 Their compound was designedto bind noncovalently with polyclonal anti-1,3-dinitrophenyl

(DNP) antibodies in situ, with the aim of enhancing the activityof 1. The activity of 1, however, was severely compromisedupon the addition of the DNP linker in their report. Parental 1has HIV-1 neutralization activity in the nanomolar range,whereas DNP linked 1 demonstrated micromolar activity inbinding studies and was not shown to neutralize HIV-1. Ourconjugate strategy differs since we use a defined monoclonalantibody covalently linked to 1. We hypothesized that ourstrategy might allow us to recover the potent activity of 1directly if the lack of activity of their DNP derivative of 1 wasdue to the noncovalent nature of attachment to antibody.Alternatively, modification of the linkage strategy to this familyof inhibitors might be key to restoring the activity of the smallmolecule.To prepare derivatives of the Bristol−Myers Squibb
compounds for conjugation to mAb, we first prepared β-lactam3 (Figure 2) derived from BMS-378806 (1) from the knowncompound 5 (Scheme 3).7 Substitution of the nitro group byalcohol 6 followed by the treatment of PCl3 gave BMS-378806derivative 7 bearing an azide group. The Huisgen reaction of 7with β-lactam 8 possessing a terminal alkyne group in the
presence of CuSO4, tris(3-hydroxypropyltriazolylmethyl)amine(THPTA), and sodium-(L)-ascorbate proceeded smoothly toyield desired compound 3 with the linker now at the Northernsector of the molecule as suggested by Spiegel et al.26
Inhibitor 2 presented us with opportunities to explore thesouthern sector of the molecule for attachment. Structure−activity relationship studies of 29−11 found that bulkysubstituents at the 4-position of the azaindole unit decreasedthe inhibition activity of the compound. Thus, a northernsector connection would be ill-advised. Protection at the 1-position also gave diminished biological activities, whereas thepiperazine of 2 was already optimized. In contrast, substitutionwas tolerated at the 7-position of the azaindole. ON the basis ofthese data, we designed 4 bearing the linker at 7-position of theazaindole (southern sector connection).Target compound 4 was synthesized as shown in Scheme 4.
Commercially available 2-hydroxy pyridine derivative 9 wassubjected to bromination to afford 10 in good yield. Thehydroxy group of 10 was allylated using Ag2CO3. Formation ofthe core azaindole structure was achieved by treatment of 11with N,N-dimethylformamide dimethylacetal followed byreduction of nitro group in the presence of Fe in AcOH. Thebromo group of 12 was replaced by a methoxy group, and 13was treated with borane-dimethylsulfide complex followed byoxidation with hydrogen peroxide to replace the terminal olefinwith a primary alcohol. The reactivity of the substituent-freenitrogen atom at the 1-position of the azaindole in 14 wasproblematic. After analysis of a number of protecting groups,we found that the trimethylsilylethoxymethyl (SEM) groupcould be utilized.27 Protection of the reactive azaindole moietyyielded 15, which was subjected to etherification with 1628 toobtain 17. Removal of the SEM group was performed usingtetrabutylammonium fluoride (TBAF). A Friedel−Craftsreaction of 18 and methyl-2-chloro-2-oxoacetate was accom-plished in the presence of an excess amount of AlCl3.
29 Theresulting compound 19 was hydrolyzed and condensed with 1-benzoylpiperazine 20 mediated by 3-(diethoxy-phosphory-loxy)-3H-benzo[d][1.2.3]triazine-4-one (DEPBT)30 to affordthe derivative of BMS-488043 21. As the final step, a Huisgenreaction was performed under conditions described forsynthesis of 3 to obtain the desired compound 4.Conjugation of agent 3 with mAb 38C2 to form 22a was
carried out by incubating 38C2 with six equivalents of 3 in 10mM PBS (pH 7.4) at room temperature for two hours (Scheme5). We evaluated the conjugation by measuring the catalyticactivity of retro-aldol reaction of methodol as per the standardmethod.15 Once a conjugate is formed, the antibody cannotcatalyze the retro-aldol reaction of methodol. Compound 22ahad undetectable catalytic activity indicating that each of thekey catalytic lysine residues had reacted with the lactam (Figure3A). The MALDI-TOF mass analysis of 22a supported theeffective conjugation of 38C2 with 3 (Figure 3B). Thedifference in mass between 38C2 and our preparation of 22a

corresponded to two equivalents of the small moleculederivative of 3. ESI-MS analysis also indicated that both ofthe two catalytic lysine moieties of 38C2 were modified (see
Supporting Information). Conjugate 22b was similarlyprepared from 4 and 38C2 and characterized (Figure 3A,C).Initially, the binding of antibody conjugates 22a and 22b to
gp120 was evaluated using an ELISA with gp120-coated plates(Figure 4). Neither unconjugated mAb or conjugate 22a boundto gp120 at 200 nM. Signal in these cases was similar to thenegative control of buffer alone (PBS). In contrast, the 22bbound strongly to gp120 at this concentration as did thepositive control broadly neutralizing antibody b12.31 The lackof binding by 22b is consistent with the results of thestructure−activity relationship study of related compounds thatthe bulky substituent at 4-position of the azaindole 1diminished the biological activity.9−11 Loss of binding activityat this concentration is consistent with the reported lowbinding activity of the DNP conjugate study and indicates thatthe northern site of the linker attachment is likely responsiblefor the loss in binding, not the fact that DNP conjugates withantibodies are reversibly formed.The anti-HIV activities of the conjugates 22a and 22b were
measured in neutralization assays with a single round ofinfectious virus (JRFL) as described previously.32 Conjugate22a showed very weak neutralization activity, consistent withthe low gp120 binding activity observed. Confirming ourhypothesis that the substituent at the northern sector 4-positionof 1 disrupted gp120 binding, neither 3 nor 7 were effective inthe assay (Figure 5A). The IC50 values of 4 and 21 with thelinker at southern 7-position were 67.5 and 25.4 nM,respectively. The conjugate 22b also blocked infection withan IC50 of 128 nM (Figure 5B). The unmodified mAb 38C2had no relevant anti-HIV activity. Evident from these studies isan impact on activity on linker attachment to the southern 7-position; however, significant neutralization activity waspreserved following linker addition at this site. We hadanticipated that conjugate 22b might exhibit significantlyenhanced activity over 4 and 21 given the bivalent display ofthe compound on the antibody following conjugation as wehave noted with other antibody targeting agents. The lack ofenhanced activity following conjugation suggests that 22b isunable to engage the HIV-1 virion in a bivalent interaction.Monovalent binding of natural antibodies that react with theCD4-binding site on gp120 has been suggested in theliterature.33 As previously reported, the chemically programmedantibody strategy has been shown to significantly extend thehalf-life of the targeting molecule relative to the unconjugatedmolecule in studies concerned with small molecule, peptide,

In conclusion, synthesis of 3 and 4 allowed for theexploration of two linkage strategies for the BMS seriesattachment inhibitors 1 and 2 and their conjugation to mAb38C2 to create chemically programmed antibodies 22a and22b. Compound 4 and its antibody conjugate 22b possessedgood biological activity and effectively neutralized HIV-1,validating a southern site for linkage of this family ofattachment inhibitors. The northern linkage site explored in 3and 22a destroyed biological activity. We anticipate thatconjugation to the antibody should improve the bioactivity andpharmacokinetic properties significantly, and therefore, 22bwarrants further testing in anti-HIV models. While the
discovery of a viable site of conjugation for this promisingfamily of attachment inhibitors35 has allowed us to establishgood antiviral activity in the case of a chemically programmedantibody, active conjugation to this family of inhibitors shouldalso facilitate their application in chemically programmedvaccines,36 chemical approaches to bispecific antibodies,37 andtopical microbicides whose construction is hereby facilitated.

ELISA assay of the BMS conjugates 22
96 well plates were coated with JR-FL gp120 (5 g/mL in PBS, pH 7.4, 50 L/well) at 4 ℃ overnight. Plates were washed
with Buffer A (1% nonfat milk and 0.1% Tween 20 in PBS, pH 7.4, 150 L/well, three times) and then blocked with 150 L
of 5% nonfat milk in PBS (pH 7.4) at 37 ℃ for 4 h. After removing the gp120 solution by decantation, varying
concentration of the conjugates were added in Buffer A (100 L/well) and incubated at 37 ℃ for 2 h. Then washing with
Buffer A (150 L/well, three times) and incubated with AP-conjugated anti-mouse (-selective, 100 L/well) (1:1000
dilution in Buffer A, pH 7.4) at 37 ℃ for 1 h. Then washing with Buffer A (150 L/well, three times) followed by washing
with PBS (pH 7.4, 150 L/well, three times), a solution of AP substrate (two tablets) in AP developer (10% diethanolamine,
0.01% MgCl2, 3 mM NaN3) was added (50 L/well) and monitored the optical density after 120 min by Mark microplate
reader (405 nm) (N = 3).

Neutralization assay of the gp120 inhibitors
Replication-incompetent HIV-1 enveloped pseudovirus was generated by cotransfection of 293T cells with JR-FL HIV-1
Env-expressing plasmid and pSG3ΔEnv as previously described.7 Serial dilutions of samples (50 l) along with wt b12,
2D7, 2G12 and an isotype control antibody, DEN3, were added to TZM-bl target cells (50 l) and preincubated at 37 ℃
for 1 h. Following incubation 250TCID50 of pseudovirus (100 l) was added to each well and incubated at 37 ℃.
Luciferase reporter gene expression was evaluated 48 h post infection. The percentage of virus neutralization at a given
antibody concentration was determined by calculating the reduction in luciferase expression in the presence of antibody
relative to virus-only wells. The antibody dilution causing 50% reduction (50% inhibitory concentration [IC50]) was
calculated by regression analysis using GraphPad Prism (N = 2).
