Me-too syntheses Comparable to every innovation, promising new drugs will be quickly followed into the market by multiple analogs, most striking in their similarity to the original computer education essay. Furthermore, HAART has been shown to reduce the synthesis of paper infections and HIV-associated cancers, contributing to the significantly decreased number of HIV- and AIDS-related deaths each year and correspondingly contributing to the much increased amount.

Hence, much innovation is essential for the success of future anti-HIV drug research. IN is an essential enzyme for viral replication, and it has no human homolog [for a recent review, see Reference [ 16 ]]. IN catalyzes the insertion of reverse transcribed viral cDNA into the host cell genome via a multi-step process.

The first step in integration occurs in the host cell cytosol and is referred to as 3'-processing. During this step, IN cleaves a dinucleotide from each viral DNA terminus at a conserved CA sequence, yielding two reactive 3' hydroxyl groups.

Following this processing step, IN associates with a number of viral and cellular proteins, forming a pre-integration complex PIC , and then migrates to the nucleus. Within the nucleus the reactive hydroxyl groups are utilized in nucleophilic attack upon the host cell genome, a process known as strand transfer [ 17 ]. IN multimerization is also required for formation of the PIC.

As a dimeric IN species is required for 3'-processing, the strand transfer step calls for a tetrameric IN arrangement. Proper integration of viral DNA into the host cell genome leads to viral protein expression, maturation, and propagation [ 18 ]. IN catalysis is vital to proper HIV-1 replication and sustained infection, and potent small-molecule IN inhibitors have been avidly sought over the last ten years as a supplement to HAART and a novel angle of attack against drug resistant viruses.

The active DKA containing compounds from this study showed a significant preference for strand transfer inhibition over that of 3'-processing in vitro. Further modification led to the inclusion of heterocyclic groups in place of the indoles, culminating in the development of multiple nitrogen and oxygen-containing heterocyclic analogs, all of which were covered in a patent [ 24 ]. S, or Z [5- 4-fluorobenzyl furanyl]hydroxy 1H-1,2,4-triazolyl propenone, was the most promising of these compounds and went on to become the first clinically tested HIV-1 IN inhibitor.

Acceptable safety and toxicology profiles were attained in animal models, and Phase I trials showed good pharmacokinetics in a group of 24 healthy HIV-negative humans [ 25 ].

However, S failed efficacy studies due to its reduction in humans at the carbon linked to the triazole heterocycle, yielding an inactive metabolite that was rapidly cleared through glucuronidation in the non-cytochrome P pathway [ 27 ], and its development was soon abandoned.

Figure 1 The structure of diketo acid-based HIV-1 integrase inhibitors. The DKA pharmacophore was subsequently transferred to a naphthyridine carboxamide core, conferring similar antiviral activity and strand transfer selectivity [ 28 ].

The most active inhibitor from this class, L, Figure 1 , showed very promising activity, with IC50 values as low as 4 nM against multidrug-resistant viruses [ 29 ]. L, soon became the second IN inhibitor to enter clinical trials. However, liver and kidney toxicity surfaced after long-term treatment in dogs, bringing a premature end to the drug's clinical progress [ 30 ].

This relative success with diketo acid structural analogs led to the derivation of a class of N-alkyl hydroxypyrimidinone carboxylic acids, which showed nanomolar activity against HIV-1 IN in enzymatic assays and a good pharmacokinetic profile modest oral bioavailability, low plasma clearance, and good half-life in rats [ 31 ].

MK, also known as raltegravir Figure 1 , emerged as the most promising pyrimidinone carboxamide derivative and soon became the first IN inhibitor to progress into Phase III clinical trials.
