Abstract
The Human immunodeficiency virus (HIV) is the causative agent of acquired immunodeficiency syndrome (AIDS), one of the most perilous diseases known to humankind. A 2023 estimate put the number of people living with HIV around 40 million worldwide, with the majority benefiting from various antiretroviral therapies. Consequently, the urgent need for the development of effective drugs to combat this virus cannot be overstated. In the realm of medicinal and organic chemistry, the synthesis and identification of novel compounds capable of inhibiting HIV enzymes at different stages of their life cycle are of paramount importance. Notably, the spotlight is on the progress made in enhancing the potency of HIV inhibitors through the use of piperazine-based compounds. Multiple studies have revealed that the incorporation of a piperazine moiety results in a noteworthy enhancement of anti-HIV activity. The piperazine ring assumes a pivotal role in shaping the pharmacophore responsible for inhibiting HIV-1 at critical stage, including attachment, reverse transcription, integration, and protease activity. This review also sheds light on the various opportunities that can be exploited to develop effective antiretroviral targets and eliminate latent HIV reservoirs. The advancement of highly potent analogues in HIV inhibitor research has been greatly facilitated by contemporary medicinal strategies, including molecular/fragment hybridization, structure-based drug design, and bioisosterism. These techniques have opened up new avenues for the development of compounds with enhanced efficacy in combating the virus.

Abstract
The acquired immunodeficiency syndrome (AIDS), caused by the human immunodeficiency virus (HIV), has been a global public health challenge for several decades. The majority of HIV infection is caused by the human immunodeficiency virus type 1 (HIV-1) which enters and infects a host cell via the cell surface proteins of CD4 as the primary receptor, and chemokine receptors CXCR4 or CCR5 as the co-receptor-then undergoing replication using the cell's intracellular machinery. Whereas many drugs targeting CCR5-mediated entry or HIV-1 replication via reverse transcriptase or proteases have long been used clinically, agents targeting CXCR4 are yet to be advanced to clinical application. Here in this review we highlight some of the strategies for and progress made in the discovery of novel small molecules, peptides, and larger molecules that target CXCR4, and their future prospects for translation into the clinic as a new class of anti-HIV therapeutics.

Abstract
Acquired immunodeficiency syndrome (AIDS) has affected millions of people worldwide. The human immunodeficiency virus (HIV) which infects T cells by using CD4 as its main receptor. Currently different treatments are available against HIV infection which can improve life expectancy of the patient but still it remains incurable. CCR5, which is also required as a co-receptor by majority of HIV strains for entry into the target cells, is now being targeted for gene therapy to develop HIV resistance in patients. In this review, we discuss different strategies that are being adapted for CCR5-gene disruption in CD4+ T cells and in hematopoietic stem cells (HSCs) to generate a HIV-resistant immune system in infected individuals. If CCR5 gene that can shape HIV-resistant T cells, it will aim in new approaches in clinical trials. But these techniques have certain weaknesses and disadvantages, and will need to be paired with other strategies to form a full HIV remedy. There is also a need to establish methods to help deter HIV re-emergence following targeted CCR5 therapy. But ultimately, this brought us a better knowledge of the road to HIV treatment.

Abstract
CXCR4, a well-studied coreceptor of human immunodeficiency virus type 1 (HIV-1) entry, recognizes its cognate ligand SDF-1α (also named CXCL12) which plays many important roles, including regulating immune cells, controlling hematopoietic stem cells, and directing cancer cells migration. These pleiotropic roles make CXCR4 an attractive target to mitigate human disorders. Here a new class of symmetrical polyamines was designed and synthesized as potential small molecule CXCR4 antagonists. Among them, a representative compound 21 (namely HF50731) showed strong CXCR4 binding affinity (mean IC50 = 19.8 nM) in the CXCR4 competitive binding assay. Furthermore, compound 21 significantly inhibited SDF-1α-induced calcium mobilization and cell migration, and blocked HIV-1 infection via antagonizing CXCR4 coreceptor function. The structure-activity relationship analysis, site-directed mutagenesis, and molecular docking were conducted to further elucidate the binding mode of compound 21, suggesting that compound 21 could primarily occupy the minor subpocket of CXCR4 and partially bind in the major subpocket by interacting with residues W94, D97, D171, and E288. Our studies provide not only new insights for the fragment-based design of small molecule CXCR4 antagonists for clinical applications, but also a new and effective molecular probe for CXCR4-targeting biological studies.

Abstract
The chemokine receptor CXCR4 is required for the entry of human immunodeficiency virus type 1 (HIV-1) into target cells and its expression correlates with more profound pathogenicity, rapid progression to acquired immunodeficiency syndrome (AIDS), and greater AIDS-related mortality. There is still no cure for AIDS and no method for preventing or eradicating HIV-1 infection. HIV-1 entry begins with the interaction of the viral envelope glycoprotein gp120 and the primary receptor CD4, and subsequently with the coreceptors, CCR5 or CXCR4, on the host cells. Blocking the interaction of HIV-1 and its coreceptors is therefore a promising strategy for developing new HIV-1 entry inhibitors. This approach has a dual benefit, as it prevents HIV-1 infection and progression while also targeting the reservoirs of HIV-1 infected, coreceptor positive macrophages and memory T cells. To date, multiple classes of CXCR4-targeted anti-HIV-1 inhibitors have been discovered and are now at different preclinical and clinical stages. In this review, we highlight the studies of CXCR4-targeted small-molecule and peptide HIV-1 entry inhibitors discovered during the last two decades and provide a reference for further potential HIV-1 exploration in the future. Impact statement This minireview summarized the current progress in the identification of CXCR4-targeted HIV-1-entry inhibitors based on discovery/developmental approaches. It also provided a discussion of the inhibitor structural features, antiviral activities, and pharmacological properties. Unlike other reviews on anti-HIV-1 drug development, which have generally emphasized inhibitors that target intracellular viral replication and host genomic integration, this review focused on the drug discovery approaches taken to develop viral-entry inhibitors aimed at disturbing the initial step of viral interaction with uninfected host cells and preventing the subsequent viral replication/genomic integration. This review amalgamated recently published and important work on bivalent CXCR4-targeted anti-HIV-1-entry candidates/conjugates, discussed the research challenges faced in developing drugs to prevent and eradicate HIV-1 infection, and provided a perspective on strategies that can lead to future drug discoveries. The findings and strategies summarized in this review will be of interest to investigators throughout the microbiological, pharmaceutical, and translational research communities.

Abstract
Viral entry, the first process in the reproduction of viruses, primarily involves attachment of the viral envelope proteins to membranes of the host cell. The crucial components that play an important role in viral entry include viral surface glycoprotein gp120, viral transmembrane glycoprotein gp41, host cell glycoprotein (CD4), and host cell chemokine receptors (CCR5 and CXCR4). Inhibition of the multiple molecular interactions of these components can restrain viruses, such as HIV-1, from fusion with the host cell, blocking them from reproducing. This review article specifically focuses on the recent progress in the development of small-molecule HIV-1 entry inhibitors and incorporates important aspects of their structural modification that lead to the discovery of new molecular scaffolds with more potency.

Abstract
The G protein-coupled receptor (GPCR) CXCR4 is a co-receptor for HIV and is involved in cancers and autoimmune diseases. We characterized five purine or quinazoline core polyamine pharmacophores used for targeting CXCR4 dysregulation in diseases. All were neutral antagonists for wild-type CXCR4 and two were biased antagonists with effects on β-arrestin-2 only at high concentrations. These compounds displayed various activities for a constitutively active mutant (CAM). We use the IT1t-CXCR4 crystal structure and molecular dynamics (MD) simulations to develop two hypotheses for the activation of the N1193.35A CAM. The N1193.35A mutation facilitates increased coupling of TM helices III and VI. IT1t deactivates the CAM by disrupting the coupling between TM helices III and VI, mediated primarily by residue F872.53. Mutants of F872.53 in N1193.35A CXCR4 precluded constitutive signaling and prevented inverse agonism. This work characterizes CXCR4 ligands and provides a mechanism for N1193.35A constitutive activation.

Abstract
Here, we report the anti-human immunodeficiency virus (HIV) potency and underlying mechanisms of a Keggin polyoxometalate (PT-1, K6HPTi2W10O40). Our findings showed that PT-1 exhibited highly potent effects against a diverse group of HIV type 1 (HIV-1) strains and displayed low cytotoxicity and genotoxicity. The time-addition assay revealed that PT-1 acted at an early stage of infection, and these findings were supported by the observation that PT-1 had more potency against Env-pseudotyped virus than vesicular stomatitis virus glycoprotein (VSVG) pseudotyped virus. Surface plasmon resonance binding assays and flow cytometry analysis showed that PT-1 blocked the gp120 binding site in the CD4 receptor. Moreover, PT-1 bound directly to gp41 NHR (N36 peptide), thereby interrupting the core bundle formation of gp41. In conclusion, our data suggested that PT-1 may be developed as a new anti-HIV-1 agent through its effects on entry inhibition.

Abstract
Acquired immunodeficiency syndrome (AIDS) is a serious worldwide disease caused by infection with the human immunodeficiency virus (HIV). C-C chemokine receptor 5 (CCR5) and C-X-C chemokine receptor 4 (CXCR4) are important coreceptors mediating HIV-1 cell entry. Many new anti-HIV drugs are currently in preclinical and clinical trials; however, drug development has proceeded slowly partly because of the lack of a high-throughput system to screen these drugs. Here, we describe the development of a novel dual-luciferase assay using a CCR5/CXCR4 promoter-driven firefly and Renilla luciferase vector (pGL4.10-RLUC-CCR5/CXCR4). Drugs were screened for the ability to regulate CCR5 and CXCR4 promoter activities. The CCR5 and CXCR4 promoters were inserted separately into the recombinant vector and transfected into the acute T lymphocyte leukemia cell line H9. Treatment of stable transfected cells with four traditional Chinese medicine compounds resulted in the dose-dependent inhibition of the CXCR4 and CCR5 promoter activities. The dual-luciferase reporter assay provides a rapid and direct method to screen anti-AIDS/HIV drugs.

Abstract
The CXC chemokine receptor 4 (CXCR4) is a highly reserved G-protein coupled 7-transmembrane (TM) chemokine receptor which consists of 352 amino acids. CXCR4 has only one endogenous chemokine ligand of CXCL12, besides several other natural nonchemokine ligands such as extracellular ubiquitin and noncognate ligand of MIF. CXCR4 strongly binds to CXCL12 and the resulting CXCLl2/CXCR4 axis is the molecular basis of their various biological functions, which include: (1) mediating immune and inflammatory response; (2) regulation of hematopoietic stem cell migration and homing; (3) an essential co-receptor for HIV entry into host cells; (4) participation in the process of embryonic development; (5) malignant tumor invasion and metastasis; (6) myocardial infarction, ischemic stroke and acute kidney injury. Correspondingly, CXCR4 antagonists find potential therapeutic applications in HIV infection, as well as hematopoietic stem cell migration, inflammation, immune-related diseases, tumor and ischemic diseases. Recently, great achievements have been made and a number of non-peptide CXCR4 antagonists with diversity scaffolds have been discovered. In this review, the discovery of small molecule CXCR4 antagonists focused on the structures, activities, evolution and development of representative CXCR4 antagonists is comprehensively described. The central role of CXCR4 in diverse cellular signaling pathways and its involvement in several diseases progressions are discussed as well.

Abstract
The function of the CXCR4/CXCL12 axis accounts for many disease indications, including tissue/nerve regeneration, cancer metastasis, and inflammation. Blocking CXCR4 signaling with its antagonists may lead to moving out CXCR4+ cell types from bone marrow to peripheral circulation. We have discovered a novel series of pyrimidine-based CXCR4 antagonists, a representative (i.e., 16) of which was tolerated at a higher dose and showed better HSC-mobilizing ability at the maximal response dose relative to the approved drug 1 (AMD3100), and thus considered a potential drug candidate for PBSCT indication. Docking compound 16 into the X-ray crystal structure of CXCR4 receptor revealed that it adopted a spider-like conformation striding over both major and minor subpockets. This putative binding mode provides a new insight into CXCR4 receptor-ligand interactions for further structural modifications.

Abstract
Chemokines are small chemotactic cytokines that are involved in the regulation of immune cell migration. Multiple functional properties of chemokines, such as pro-inflammation, immune regulation, and promotion of cell growth, angiogenesis, and apoptosis, have been identified in many pathological and physiological contexts. Human immunodeficiency virus (HIV) infection is characterized by persistent inflammation and immune activation during both acute and chronic phases, and the "cytokine storm" is one of the hallmarks of HIV infection. Along with immune activation after HIV infection, an extensive range of chemokines and other cytokines are elevated, thereby generating the so-called "cytokine storm." In this review, the effects of the upregulated chemokines and chemokine receptors on the processes of HIV infection are discussed. The objective of this review was to focus on the main chemokines and chemokine receptors that have been found to be associated with HIV infection and latency. Elevated chemokines and chemokine receptors have been shown to play important roles in the HIV life cycle, disease progression, and HIV reservoir establishment. Thus, targeting these chemokines and receptors and the other proteins of related signaling pathways might provide novel therapeutic strategies, and the evidence indicates a promising future regarding the development of a functional cure for HIV.

Abstract
CXCR4 (C-X-C Chemokine Receptor type 4) and its natural ligand SDF-1α (Stromal-Derived-Factor-1α) are involved in a number of physiological and pathological processes including cancer spread and progression. Over the past few years, numerous CXCR4 antagonists have been identified and currently are in different development stages as potential agents for the treatment of several diseases involving the CXCR4/SDF-1α axis. Herein, we focus on small molecules reported in literature between 2013 and 2017, claimed as CXCR4 antagonists and potentially useful in the treatment of cancer and other diseases where this receptor is involved. Most of the compounds resulted from a chemical optimization of previously identified molecules and some of them could represent suitable candidates for the development of advanced anticancer agents.

Abstract
CXCR4 antagonists (e.g., PlerixaforTM ) have been successfully validated as stem cell mobilizers for peripheral blood stem cell transplantation. Applications of the CXCR4 antagonists have heralded the era of cell-based therapy and opened a potential therapeutic horizon for many unmet medical needs such as kidney injury, ischemic stroke, cancer, and myocardial infarction. In this review, we first introduce the central role of CXCR4 in diverse cellular signaling pathways and discuss its involvement in several disease progressions. We then highlight the molecular design and optimization strategies for targeting CXCR4 from a large number of case studies, concluding that polyamines are the preferred CXCR4-binding ligands compared to other structural options, presumably by mimicking the highly positively charged natural ligand CXCL12. These results could be further justified with computer-aided docking into the CXCR4 crystal structure wherein both major and minor subpockets of the binding cavity are considered functionally important. Finally, from the clinical point of view, CXCR4 antagonists could mobilize hematopoietic stem/progenitor cells with long-term repopulating capacity to the peripheral blood, promising to replace surgically obtained bone marrow cells as a preferred source for stem cell transplantation.

This
review focuses on the construction and application of structural chemokine
receptor models for the elucidation of molecular determinants of chemokine
receptor modulation and the structure-based discovery and design of
chemokine receptor ligands. A comparative analysis of ligand binding
pockets in chemokine receptors is presented, including a detailed
description of the CXCR4, CCR2, CCR5, CCR9, and US28 X-ray structures,
and their implication for modeling molecular interactions of chemokine
receptors with small-molecule ligands, peptide ligands, and large
antibodies and chemokines. These studies demonstrate how the integration
of new structural information on chemokine receptors with extensive
structure–activity relationship and site-directed mutagenesis
data facilitates the prediction of the structure of chemokine receptor–ligand
complexes that have not been crystallized. Finally, a review of structure-based
ligand discovery and design studies based on chemokine receptor crystal
structures and homology models illustrates the possibilities and challenges
to find novel ligands for chemokine receptors.

Abstract
CXCR4 plays vital roles in HIV-1 life cycle for it's essential in mediating the interaction of host and virus and completing the entry process in the lifecycle of HIV-1 infection. Compared with some traditional targets, CXCR4 provides a novel and less mutated drug target in the battle against AIDS. Its antagonists have no cross resistance with other antagonists. Great achievements have been made recent years and a number of small molecular CXCR4 antagonists with diversity scaffolds have been discovered. In this review, recent advances in the discovery of CXCR4 antagonists with special attentions on their evolution and structure-activity relationships of representative CXCR4 antagonists are described. Moreover, some classical medicinal chemistry strategies and novel methodologies are also introduced.

Abstract
The early effectiveness of combinatorial antiretroviral therapy (cART) in the treatment of HIV infection has been compromised to some extent by rapid development of multidrug-resistant HIV strains, poor bioavailability, and cumulative toxicities, and so there is a need for alternative strategies of antiretroviral drug discovery and additional therapeutic agents with novel action modes or targets. From this perspective, we first review current strategies of antiretroviral drug discovery and optimization, with the aid of selected examples from the recent literature. We highlight the development of phosphate ester-based prodrugs as a means to improve the aqueous solubility of HIV inhibitors, and the introduction of the substrate envelope hypothesis as a new approach for overcoming HIV drug resistance. Finally, we discuss future directions for research, including opportunities for exploitation of novel antiretroviral targets, and the strategy of activation of latent HIV reservoirs as a means to eradicate the virus.

Abstract
Human immunodeficiency virus (HIV), the causative agent of acquired immune deficiency syndrome, has claimed innumerable lives in the past. Many biomolecules which suppress HIV replication and also other biomolecules that inhibit enzymes essential to HIV replication have been reported. Proteins including a variety of milk proteins, ribosome-inactivating proteins, ribonucleases, antifungal proteins, and trypsin inhibitors; peptides comprising cathelicidins, defensins, synthetic peptides, and others; polysaccharides and polysaccharopeptides; nucleosides, nucleotides, and ribozymes, demonstrated anti-HIV activity. In many cases, the mechanism of anti-HIV action has been elucidated. Strategies have been devised to augment the anti-HIV potency of these compounds.

Abstract
CXCR4 and its ligand CXCL12 mediate the homing of progenitor cells in the bone marrow and their recruitment to sites of injury, as well as affect processes such as cell arrest, survival, and angiogenesis. CXCL12 was long thought to be the sole CXCR4 ligand, but more recently the atypical chemokine macrophage migration inhibitory factor (MIF) was identified as an alternative, non-cognate ligand for CXCR4 and shown to mediate chemotaxis and arrest of CXCR4-expressing T-cells. This has complicated the understanding of CXCR4-mediated signaling and associated biological processes. Compared to CXCL12/CXCR4-induced signaling, only few details are known on MIF/CXCR4-mediated signaling and it remains unclear to which extent MIF and CXCL12 reciprocally influence CXCR4 binding and signaling. Furthermore, the atypical chemokine receptor 3 (ACKR3) (previously CXCR7) has added to the complexity of CXCR4 signaling due to its ability to bind CXCL12 and MIF, and to evoke CXCL12- and MIF-triggered signaling independently of CXCR4. Also, extracellular ubiquitin (eUb) and the viral protein gp120 (HIV) have been reported as CXCR4 ligands, whereas viral chemokine vMIP-II (Herpesvirus) and human β3-defensin (HBD-3) have been identified as CXCR4 antagonists. This review will provide insight into the diversity and inter-connections in the CXCR4 receptor/ligand family. We will discuss signaling pathways initiated by binding of CXCL12 vs. MIF to CXCR4, elaborate on how ACKR3 affects CXCR4 signaling, and summarize biological functions of CXCR4 signaling mediated by CXCL12 or MIF. Also, we will discuss eUb and gp120 as alternative ligands for CXCR4, and describe vMIP-II and HBD-3 as antagonists for CXCR4. Detailed insight into biological effects of CXCR4 signaling und underlying mechanisms, including diversity of CXCR4 ligands and inter-connections with other (chemokine) receptors, is clinically important, as the CXCR4 antagonist AMD3100 has been approved as stem cell mobilizer in specific disease settings.
