9EOU – Crystal Structure of the b1b2 domains from Human Neuropilin-1 in complex with a peptide.

The osteopontin-derived peptide FOL-005 stimulates hair growth. Using ligand-receptor glyco-capture technology we identified neuropilin-1 (NRP-1), a known co-receptor for vascular endothelial growth factor (VEGF) receptors, as the most probable receptor for FOL-005 and the more stable analogue FOL-026. X-ray diffraction and microscale thermophoresis analysis revealed that FOL-026 shares binding site with VEGF in the NRP-1 b1-subdomain.

9FXZ – Galectin-8 N-terminal carbohydrate recognition domain in complex with 4-(bromophenyl)phthalazinone D-galactal ligand.

Galectin-8 contains two different carbohydrate recognition domains (CRDs). Selective inhibitors for at least one CRD are desirable for galectin-8 biology studies and potentially for pharmacological purposes. Structure-guided design led to the discovery of potent and selective glycomimetic–heterocycle hybrid ligands, with a 4-(p-bromophenyl)phthalazinone derivative displaying a 34 μM Kd for galectin-8N (N-terminal CRD), no binding to galectin-8C (C-terminal CRD), -1, -3, -4N, -7, -9C, or -9N, and >40-fold selectivity over galectin-4C. Selectivity was achieved with the halogenated 4-phenylphthalazinone moiety occupying a galectin-8N-specific sub-pocket. A 1.30 Å resolution X-ray structure revealed the phthalazinone moiety stacking with Arg45 and the 4-bromophenyl moiety stacking both Arg59 and Tyr141 of galectin-8N.

8RP8 – Structure of K2 Fab in complex with human CD47 ECD
8RPB – Structure of S79 Fab in complex with IgV domain of human PD-L1

In contrast to natural antibodies that rely mainly on the heavy chain to establish contacts with their cognate antigen, we have developed a bispecific antibody format in which the light chain (LC) drives antigen binding and specificity. To better understand epitope-paratope interactions in this context, we determined the X-ray crystallographic structures of an antigen binding fragment (Fab) in complex with human CD47 and another Fab in complex with human PD-L1. These Fabs contain a κ-LC and a λ-LC, respectively, which are paired with an identical heavy chain (HC). The structural analysis of these complexes revealed the dominant contribution of the LCs to antigen binding, but also that the common HC provides some contacts in both CD47 and PD-L1 Fab complexes. The anti-CD47 Fab was affinity optimized by diversifying complementary-determining regions of the LC followed by phage display selections.

J Colloid Interface Sci. 672, 244-255. doi: 10.1016/j.jcis.2024.05.157.


In this work, the behavior of three model proteins (human growth hormone, bovine serum albumin, and β-lactoglobulin) was investigated in the presence of the anionic surfactant sodium dodecylsulfate, the nonionic surfactant β-dodecylmaltoside, and mixtures of both surfactants. The transitions occurring to the proteins were determined using intrinsic fluorescence spectroscopy and far-UV circular dichroism. Based on these results, we developed a detailed interaction model for human growth hormone. Using nuclear magnetic resonance and contrast-variation small-angle neutron scattering, we studied the amino acid environment and the conformational state of the protein.

4Q26 – Crystal Structure of Galectin-1 in Complex with N-Acetyllactosamine

We have previously described a new series of selective and orally available galectin-1 inhibitors resulting in the thiazole-containing glycomimetic GB1490. Here, we show that the introduction of polar substituents to the thiazole ring results in galectin-1-specific compounds with low nM affinities. X-ray structural analysis of a new ligand-galectin-1 complex shows changes in the binding mode and ligand-protein hydrogen bond interactions compared to the GB1490-galectin-1 complex. These new high affinity ligands.

8PBO – Deep interactome learning for generative drug design

De novo drug design aims to generate molecules from scratch that possess specific chemical and pharmacological properties. The group of Professor Gisbert Schneider at ETH Zurich, presents a computational approach utilizing interactome-based deep learning for ligand-based and structure-based de novo design of drug-like molecules in this publication. New ligands targeting the binding site of the human peroxisome proliferator-activated receptor subtype gamma (PPARgamma, a protein from our FastLane™ Premium library) were generated. The system considers synthesizability, novelty, bioactivity, and physicochemical properties for ligand design. The binding mode of the ligand was confirmed by the crystal structure of the protein-ligand complex provided by the SARomics team. The structure of the complex shows that the ligand effectively interacts with the receptor in a canonical binding mode, while also demonstrating the desired selectivity towards the receptor and favorable ADME properties.

8OJP – Human galectin 1 in complex with inhibitor

A new series of orally available α-d-galactopyranosides with high affinity and specificity toward galectin-1 have been discovered. High affinity and specificity were achieved by changing six-membered aryl-triazolyl substituents in a series of recently published galectin-3-selective α-d-thiogalactosides (e.g., GB1107 Kd galectin-1/3 3.7/0.037 μM) for five-membered heterocycles such as thiazoles. One compound, GB1490 (Kd galectin-1/3 0.4/2.7 μM), was selected for further characterization toward a panel of galectins showing a selectivity of 6- to 320-fold dependent on galectin. The X-ray structure of GB1490 bound to galectin-1 reveals the compound bound in a single conformation in the carbohydrate binding site.

This study aimed to develop a monoclonal antibody against SARS-CoV-2 from B cells of recovered COVID-19 patients, which might have beneficial therapeutic purposes for COVID-19 patients. The authors generated human monoclonal antibodies (hmAbs) against the receptor binding domain (RBD) protein of SARS-CoV-2 using developed hybridoma technology. The isolated hmAbs against the RBD protein (wild-type) showed high binding activity and neutralized the interaction between the RBD and the cellular receptor angiotensin-converting enzyme 2 (ACE2) protein. Epitope binning and crystallography results displayed target epitopes of these antibodies in distinct regions beneficial in the mix as a cocktail.

8F0L – Crystal Structure of the Human T cell Receptor CD3(EPSILON) N-Terminal Peptide Complexed with ADI-26906 FAB.

Bispecific antibodies continue to represent a growth area for antibody therapeutics, with roughly a third of molecules in clinical development being T-cell engagers that use an anti-CD3 binding arm. Using insights from the crystal structure of anti-Hu/Cy CD3 antibody ADI- 26906 in complex with CD3ε and antibody engineering using a yeast-based platform, the authors have derived high-affinity CD3 antibody variants with very low polyreactivity and significantly improved biophysical developability. Comparison of these variants with CD3 antibodies in the clinic (as part of bi- or multi- specifics) shows that affinity for CD3 is correlated with polyreactivity. The engineered CD3 antibodies break this correlation, forming a broad affinity range with no to low polyreactivity. Such antibodies will enable bispecifics with improved pharmacokinetic and safety profiles and suggest engineering solutions that will benefit the large and growing sector of T-cell engagers.

Ligand selectivity hotspots in serotonin GPCRs.
Trenda Pharm. Sci. 44, 978-990. https://doi.org/10.1016/j.tips.2023.09.012

Serotonin is a neurotransmitter involved in the regulation of numerous physiological processes. Its action is also modulated by drugs in the treatment of schizophrenia, depression, migraine, and obesity. However, these drugs typically have adverse effects caused by promiscuous binding across 12 serotonin and more than 20 homologous receptors. This review maps 19 ‘selectivity hotspots’, that are non-conserved binding site residues that control selectivity via favorable target interactions or repulsive ‘off-target’ contacts. It also reviews functional rationale from observed ligand-binding affinities and mutagenesis effects.

7R58 – Crystal structure of the GPVI-glenzocimab complex

Platelet glycoprotein VI (GPVI) is attracting interest as a potential target for the development of new antiplatelet molecules with a low bleeding risk. A cocrystal of glenzocimab with an extracellular domain of monomeric GPVI was obtained and its structure determined to a resolution of 1.9 Å. The data revealed that (1) glenzocimab binds to the D2 domain of GPVI, GPVI dimerization was not observed in the crystal structure because glenzocimab prevented D2 homotypic interactions and the formation of dimers that have a high affinity for collagen and fibrin; and (2) the light variable domain of the GPVI-bound Fab causes steric hindrance that is predicted to prevent the collagen-related peptide (CRP)/collagen fibers from extending out of their binding site and preclude GPVI clustering and downstream signaling.

7YXU – Crystal structure of agonistic antibody 1618 fab domain bound to human 4-1BB

4–1BB (CD137) is an activation-induced costimulatory receptor that regulates immune responses of activated CD8 T and natural killer cells, by enhancing proliferation, survival, cytolytic activity, and IFNγ production. To minimize systemic immune toxicities and enhance activity at the tumor site, the authors have developed a novel bispecific antibody that stimulates 4–1BB function when co-engaged with the tumor-associated antigen 5T4. ALG.APV-527 was built on the basis of the ADAPTIR bispecific platform with optimized binding domains to 4–1BB and 5T4 originating from the ALLIGATOR-GOLD human single-chain variable fragment library. Using X-ray crystallography The epitope of ALG.APV-527 was determined to be located at domain 1 and 2 on 4–1BB.

– Crystal structure of ALPN-202 (engineered CD80 vIgD) in complex with PD-L1

The CD80 vIgD from ALPN-202 was co-crystallized with WT PD-L1 ECD and used to determine the structure of the CD80 vIgD:PD-L1 complex. The paper shows that a therapeutic ALPN-202 enhances T cell activation and anti-tumor efficacy in cell-based assays and mouse tumor models more potently than checkpoint blockade alone and thus has the potential to generate potent, clinically meaningful anti-tumor immunity in humans.

Serotonin (or 5-hydroxytryptamine, 5-HT) is an important neurotransmitter that activates 12 different G protein-coupled receptors (GPCRs) through selective coupling of Gs, Gi, or Gq proteins. The structural basis for G protein subtype selectivity by these GPCRs remains elusive. The paper reports the structures of the serotonin receptors 5-HT4, 5-HT6, and 5-HT7 with Gs, and 5-HT4 with Gi1. The structures reveal that transmembrane helices TM5 and TM6 alternate lengths as a macro-switch to determine receptor’s selectivity for Gs and Gi, respectively.

Serotonin, or 5-hydroxytryptamine (5-HT), is a neurotransmitter that activates the largest subtype family of G-protein-coupled receptors (GPCR). Drugs that target 5-HT1A, 5-HT1D, 5-HT1E and other 5-HT receptors are used to treat numerous disorders. The paper reports five structures of 5-HT receptor–G-protein complexes: 5-HT1A in the apo state, bound to 5-HT or bound to the antipsychotic drug aripiprazole; 5-HT1D bound to 5-HT; and 5-HT1E in complex with a 5-HT1E- and 5-HT1F-selective agonist, BRL-54443.
