In these reactions, it is also possible to make use of variants which are themselves known to those of ordinary skill in this art but are not mentioned in greater detail. The general procedures for making the compounds claimed in this invention can be readily understood and appreciated by one skilled in the art from viewing the following schemes. The examples also include methods for testing such compounds in biophysical, biochemical, and cellular assays. The compounds illustrated in the examples are not, however, to be construed as forming the only genus that is considered as the disclosure.
[00237] Unless otherwise specifically indicated, all reagents are commercially available, known in the literature, or readily synthesized by one skilled in the art. lire general route applied to the synthesis of compounds of Formula (II) (e.g, Compounds A, B, C, D) is described in the Schemes that follow. In some instances, the order of carrying out the reaction steps in the schemes may be varied to facilitate the reaction or to avoid unwanted reaction products. Additionally, various protecting group strategies familiar to one skilled in the art of organic synthesis and solid phase peptide synthesis may be employed to facilitate the reaction, to improve yield and purity, or to avoid unwanted reaction products.
[00238] All reagents and solvents were purchased from commercial sources and used without further purification unless otherwise noted. All temperatures are in degrees Celsius (°C), and ambient temperature or room temperature (RT) is 20 °C. Most compounds were purified by reversed-phase preparative high-performance liquid chromatography (HPLC) or mediumpressure liquid chromatography (MPLC) on silica gel. The course of the reactions was followed by liquid chromatography / mass spectrometry (LC-MS) or Ultra performance liquid chroma.iogra.phy / mass spectrometry (UPLC-MS); electrospray ionization (ESI); UV detection at 254 nm). Proton, fluorine, and carbon magnetic resonance (’H, 19F and BC NMR) spectra were recorded on a 300, 400, 500, or 600 MHz Varian or Bruker spectrometer, and chemical shifts are reported in parts per million (ppm) relative to tetramethylsilane and referenced to residual solvent. Coupling constants are reported in hertz. 5H NMR data are reported as given here: chemical shift (multiplicity [singlet (s), doublet (d), triplet (0. quartet (q), doublet of doublets (dd), doublet of triplets (dt), triplet of doublets (td), triplet of triplets (tt), doublet of doublet of doublets (ddd), multiplet (m), and broad singlet (br. s)], coupling constant [Hz] and integration). Reactions sensitive to moisture or air were performed under nitrogen or argon using anhydrous solvents and reagents. The progress of reactions was determined by either analytical thin layer chromatography (TLC) usually performed with pre-coated TLC plates (E. Merck, Darmstadt, Germany), silica gel 60F-254, layer thickness 0.2.5 mm or liquid chromatography-mass spectrometry (LC-MS).

[00240] The term "‘w / w' means weight of compound to total weight. For example, NaH 60% w / w means 60 parts by weight NaH to 100 parts total weight. [00241 ] The following examples are provided so that the invention might be more fully understood. These examples are illustrative only and should not be construed as limiting the invention in any way. Wherein a racemic mixture is produced, the enantiomers may be separated using SFC reverse or normal phase chiral resolution conditions either after isolation of the final product or at a suitable Intermediate, followed by processing of the single isomers individually. It is understood that alternative methodologies may also be employed in the synthesis of these key intermediates and examples. Asymmetric methodologies (e.g., chiral catalysis, auxiliaries, biocatalytic process) may be used where possible and appropriate. The exact choice of reagents, solvents, temperatures, and other reaction conditions depends upon the nature of the intended product.

[00248] During peptide chain elongation, the a-amino group of each amino acid was protected with a 9#-fluoren-9-ylmethoxycarbony1 group (Fmoc). To avoid any side reactions during the chain elongation steps, any reactive amino acid side chains also carry' acid-labile protecting groups, effectively masking the reactive groups until removal upon treatment with strong acid. After completion of each coupling step, the Fmoc group of the TV-terminal amino acid was removed with piperidine or 4-methylpiperidine and the resin was thoroughly washed to prepare for the coupling of the subsequent Fmoc-protected ammo acid derivative. |00249] The side chain protecting groups used were: 1. terf-butyl (?Bu) for a-Me-t.-Ser (aMeS), L-Ser (S), L-Tyr, (Y) PhedCOOH, A-Me-t-Glu (NMeE); 2. trityl (Til) for L-Asn (N), L-Cys (C); 3. rerLbutoxy-carbonyl (Boc) forL-Trp (W). a-Me-L-Trp (aMeW), L-His (H).

[00252] Reactions were topically performed at a 50 pmol scale using Rink Amide MBHA LL resin (100-200 mesh, 0.4 mmol / g loading, 1% DVB cross-linked polystyrene, Novabiochem*). All the amino acids were dissolved at a 0.2 M concentration in anh. DMF orNMP. The amino acids were activated with equimolar amounts of Oxyma Pure solution (0.5 M in anh, DMF), and a 2-fold molar excess of DIC solution (0.5 M in anh. DMF). |00253] Every synthesis cycle included: (1) Fmoc amino acid deprotection by 20% v / v piperidine or V-methylmorpholine (NMM) in anh.

Procedure For Human STNFRl-Peptide Displacement Assay [00277| The affinity was determined using LanthaScreen Eu-based time-resolved fluorescence resonance energy transfer (TR-FRET)-based binding assay.
[00278] A TR-FRET assay measuring the displacement of biotinylated peptide SEQ ID NO:4 from human sTNFRl in a pre-formed complex by a macrocyclic peptide yields the affinity CKf'pp) of the cyclic peptide for sTNFRl. The reagents for the assay include: the C -tenmnally 6His-iagged sTNFRl (residues 1-211) protein purified from a S / 21 baculovirus expression system, the biotin-tagged B0372 peptide described in section '‘Preparation of Final Compounds’’, part E, the LanthaScreen™ anti-His Tag Europium donor (Life Technologies Corporation (San Diego, CA), cat. ft PV5597), and a streptavidin-conjugate Alexa Fluor™ 647 acceptor (Invitrogen (Waltham, MA), cat. # S32357). Time-resolved TR-FRET is achieved when sTNFRl is bound to biotinylated peptide SEQ ID NO:4 through coupling of the donor and acceptor FRET pair.
[00279] 100 nM biotinylated peptide SEQ ID NO:4 and 0.25 nM sTNFRl -6His are added to a binding buffer (lx DPBS, Gibed™, cat. # 20012-027 with 0.1% BSA and 0.05% Tween® 20) to form the protein-peptide complex. 100 nM biotinylated peptide SEQ ID NO:4 was chosen as it reflects the ~Kd for this complex. After 30 min at ambient temperature, each test peptide (2 mM stock in DMSO) is titrated in a 20 point, ~3-foId discrete dose-response using an acoustic-dispense liquid handler. Specifically, 80 nt of peptide / DMSO is transferred into a ProxiPlate-384 Plus 384-udi assay plate (PerkinElmer, cat. # 6008289). To this plate, 8 uL of the previously formed sTNFRl - biotiny lated peptide SEQ ID NO:4 complex is added and allowed to reach binding equilibrium with the test peptide at ambient temperature for 90 min. For TR-FRET detection. 8 uL of 0.25 nM of LanthaScreen™ anti-His Tag Europium and 25 nM of streptavidin-conjugate Alexa Fluor™ 647 in the same binding buffer are added to the assay plate and read on an EnVision® plate reader (PerkinElmer (Boston, MA)) after a 90 min final incubation.
[00280] The TR-FRET signal is measured with the following EnVision'® settings: excitation laser at 337 nm: emission! = 615 nm, emission2 = 665 nm, LANCE / DELFIA dichroic mirror, delay time = 100 ms. The signal of each well is determined as the ratio of the emission at 665 nm to that at 615 nm. Percent displacement is determined by normalization to control wells containing DMSO (0%) or a saturating concentration of a displaceable peptide (100%). The %-effect as a function of peptide concentration is fit to a five-parameter logistic fit based on the Morrison equation to account for tight binding kinetics. The inflection point of the 5-parameter fit is the measured Adapp reported in Table 3. It should be noted that peptides with weaker binding affinity where tight binding was not observed under these assay conditions were titrated with 10 pts titration range and dose-response curves were analyzed using a 4-parameter logistic model to calculate TCso values (Table 3). sTNFRl sequence (SEQ ID NO:15): LVPHLGDREKRDSVCPQGKYIHPQNNSICCTKCHKGTYLYNDCPGPGQDTDCRECESGSFTASENHL RHCLSCSKCRKEMGQVEISSCTVDRDTVCGCRKNQYRHYWSENLFQCFNCSLCLNGTVHLSCQEKQN TVCTCHAGFFLRENECVSCSNCKKSLECTKLCLPQIENVKGTEDSGTTGGGLNDIFEAQKIEWHERE VLFQGPHHHHHHGSWSHPQFEK 8.2.2.

[00289] After 1 h incubation, the sample was divided into 2 aliquots, and a solution of 125 mM zinc chloride solution was added to one of the aliquots to a final concentration of 1 mM. Broad screening of crystallization conditions was performed using commercially available screens at 18 °C. Screening set-up was performed using a Mosquito (TTP Labtech) dispensing 200 nL of sample solution with or without exogenous zinc in two separate sub-wells, to which 100-200 nL of precipitant solution was added. The mixture was incubated at 18 °C in a Rockimager (Formulatrix). Crystals appeared between a time period of 2 to 45 days. For flashfreezing and data collection, a cryoprotectant solution at a pH and a precipitant concentration matching the crystallization conditions and augmented with 20% v / v glycerol was added to the crystallization drop. The crystals were then harvested with a LithoLoop (Molecular Dimensions) and flash-frozen in liquid nitrogen. [0029()] Data collection was performed either at the Industrial Macromolecular Consortium Association (IMCA) beamline at the Advanced Photon Source (APS), or at the macromolecular crystallography beam line at the Canadian Light Source (CLS). Data were processed using the autoPROC (Global Phasing) software with calls to XDS, POINTLESS (CCP4) and STARANISO (Global Phasing) for integration, space group determination and scaling, respectively. The structure wras solved by molecular replacement using the MOLREP program (CCP4). Structures were refined using COOT (CCP4) and autoBUSTER (Global Phasing). 8.3.3. Cryo-EM Grid Preparation and Data Collection
[00291] TNFa, TNFR V7 construct, and Compound B were mixed in the final buffer composition w?as 20 mM Tris, pH 8.0, and 100 mM NaCI at a molar ratio of 1:3:6 and incubated for an hour in ice. Aliquots (3 pL) of purified complex were applied to glow-discharged (20 s on carbon side) C-flat 20 nm thickness holey carbon-on-gold grids (300 mesh, RI .2 / 1.3). The grids were blotted for 3 s at 95% humidity and plunge-frozen into liquid ethane using a Vitrobol Mark IV (Thermo Fisher Scientific). Grids were imaged on a 300 keV Titan Krios cryo-electron microscope (Thermo Fisher Scientific) equipped with an energy filter (Galan GIF BioQuantum) and a post-GIF Gatan K3 Summit direct electron detector. Images were taken on the K3 camera in dose-fractionation mode at a calibrated magnification of 105000. corresponding to 0.84 A per physical pixel (0.42 A per super-resolution pixel). The dose fractionation on the specimen was set to be 1.0625 electrons per A2 per frame and the total number of frames was 40, resulting in a total dose of 42.5 electrons per A2. An energy slit with a width of 20 eV was used during data collection. Fully automated data collection was carried out using Latitude in Gatan Imaging Suite (Gatan Inc.) with a nominal defocus range set from -0.6 to -2.0 pm. Image Shift was used with nine exposure groups per stage shift to improve the throughput of data collection. A total of 12000 movies were collected for the sample. 8.3.4. Cryo-EM Data Processing
[00292] The cryoSPARC Live application of cryoSPARC v2 (Structure Biotechnology') was used to streamline the movie processing, CTF estimation, particle picking, and 2D classification. Preprocessing involved anisotropic motion correction and local CTF estimation. The data were curated by keeping only data with better than 6 A determined by CTF fit resolution. Particle picking started with blob picking —150 A in diameter. Once a small set of particles was extracted and 2D class averages were obtained, the good 2D classes were used as templates for picking on the entire dataset. Then ab initio 3D reconstruction was carried out in cryoSPARC v2. Homogenous refinement coupled with nonuniform and global CTF refinements gave the final 3D reconstructions at 3.2 A. The structure was built starting from atomic models of close homologs. Manual adjustments to the models were performed using Coot and automated refinement was performed using Phenix. Coordinates and restraints for peptides were generated using Grade (Global Phasing Ltd.) and was manually fitted into the density' using real-space refinement in Coot and further refined using Phenix. Model quality was assessed using Molprobity as implemented in Phenix.
